Brauer’s Sylphrena

Expected: April 2026

Puppies from this litter will be Embarked prior to going to their new homes. We expect the litter to average 95%+ Gray Wolf. This litter will be whelped and raised inside our home. Puppies will nurse naturally with mama Syl, but will also receive supplemental bottle feeding and intensive hands-on handling and socialization daily. We use Puppy Culture as the foundation of our puppy raising, socialization, and introductory training process. Puppy Culture includes Early Neurological Stimulation, age-appropriate activities and brain games for each stage of development, and a strong focus on building positive associations with each puppy’s interactions with new people, places, and objects.

Our dams are dewormed before and during pregnancy, and the litter and nursing dam are dewormed every 2 weeks to prevent internal parasites. Our puppies are microchipped and receive age-appropriate vaccinations from our veterinarian, as well as a fecal test, full-body evaluation and Health Certificate prior to each puppy going to their new homes.

Puppies from this litter will be sent home with a puppy package that includes (but is not limited to): fully-signed ownership contract; vet records and Health Certificate; 7-generation pedigree; copies of parents’ OFA health test results; a new collar with tags, leash, and harness; brand-new hard plastic travel crate; blanket; toys; treats; cleaning supplies for the trip home; bag of food bowls.

Non-breeding puppies from this litter are priced at $4,000.00 USD. Deposits are only accepted AFTER a fully completed application has been and the applicant has passed our interview process and signed our Deposit Contract. Please click below to begin our application process.

What we expect from this litter:

Our goal for this litter is to produce high content wolfdogs who can be excellent family pets. High content wolfdogs are not wild animals by any stretch of the imagination; they are selectively bred companions. As such, we believe strongly that they should be able to thrive as members of the family, be able to live politely indoors with proper boundaries and structure, and enjoy being included in the day-to-day activities of their owners. We feel that Genn and Syl both embody this type of companion temperament, and expect their puppies will, as well. We do not expect seasonal aggression from these puppies once they reach sexual maturity, although we do expect to see at least moderate same-sex aggression and do not advise females being allowed to interact with each other once they are nearing sexual maturity in their second winter. Genn and Syl are both on the small end for high content wolfdogs - Genn is 28.5 inches tall and weighs 84 lbs, and Syl is 27.5 inches tall and weighs 70 lbs. That being said, both Genn and Syl come from truly LARGE parents who are 32-33 inches tall and weigh around 90-110 lbs, so it’s entirely possible that the genetics for larger offspring are lurking in Genn and Syl’s genes! In general, we expect their puppies will likely end up around 28-30 inches tall.

Genn is already a rather exceptionally chill and easy high content wolfdog in many aspects, which is very typical for the Cottonwoodz wolfdog line that he comes from. He sleeps in his crate at night and prefers to spend most of the day snoozing on the couch every chance he gets. He lives for couch naps, belly rubs, and treats, in that order. He does not get grouchy at all in the winter when hormones are in full force for breeding season, remaining extremely affectionate and easy to handle year-round. He’s not destructive in the house and, while we don’t leave him loose without supervision inside, he has never given us any issues as an indoor pet. Genn is affectionately nicknamed the fun uncle in our household, because he absolutely loves our Tamaskans and our Wolven Gazehound, Corus. He loves to galumph along behind them as they play chase and wrestle with each other in the yard, a goofy third wheel to their shenanigans. Genn remains neutral to other males, as long as they’re neutral/polite with him. If they’re rude, that gets on his nerves, and he’ll reciprocate if they’re trying to cause trouble. He absolutely adores Corus, who is still intact (we constantly joke they are husbands). While most wolfdogs tend to be fairly disinterested in training and require above average effort to maintain their attention and motivation, Genn absolutely loves training and is highly enthusiastic to learn new cues and show off what he knows for both praise and treats. He is strongly food motivated and responds best to positive reinforcement training with minimal consequences that are consistent but fair, to proof his response time and impulse control. Despite being rather lazy at home, Genn is always down for an adventure with us, and he really enjoys going on trips into town with us to pet-friendly places. We haven’t been super athletically active, due to our own physical limitations, but Genn is always happy whenever we’re up for a trip to the park or a hike on the trails. His low-key, affectionate, goofy, and generally “easy” temperament that the Cottonwoodz line is so well-known for is something we look forward to seeing him pass down.

Syl is affectionately nicknamed our “toasted marshmallow”, and she certainly lives up to it. She is a very sweet, snuggly, and soft-natured girl who’s happy to be included in whatever we do. She will somersault into our lap for cuddles and loves belly rubs and butt scritches. She comes from a line of wolfdogs that has been selectively bred to be excellent companions and even has relatives who work in the film industry! Syl doesn’t experience any seasonal aggression at all, instead becoming even more affectionate during the breeding season. Syl does show some same-sex aggression towards other female dogs, so we don’t allow her to interact with our other girls, but she shares a fence line with them with no issues and sometimes shows affection towards our young Tamaskan Dog girls through the fence. Syl absolutely loves training and is very enthusiastic about learning new behaviors and showing off what she knows for treats. Her high food drive definitely helps to keep her motivated during training sessions, and she responds best to positive reinforcement training methods. Syl isn’t a huge fan of going into crowded public places, but she does excellently on her trips to the vet and remains calm and well-mannered throughout her appointments. She really enjoys trail walks at the state parks that we’ve gotten to visit, as well. She is extremely easy to handle and will happily dangle in Dustin’s arms when he picks her up. She even falls asleep in the bathtub, and we have to prop her up just to rinse her off! She’s an incredibly loving and affectionate girl and we’re so excited to see her pass that down to her puppies.

Possible Puppy Colors…

Genn’s coat color genetics are E/E KB/ky at/at S/S

Syl’s coat color genetics are E/E ky/ky Ay/at S/S

It is important to note that, although ‘at’ stands for Black & Tan and usually indicates that a dog will be colored like a Doberman Pinscher or Rottweiler, there appears to be some kind of undiscovered wild-type gene that is pretty much identical in expression to Agouti Wild “wolf grey” coloration. The computer doesn’t know what else to label it as, so this wild-type mystery gene gets lumped in with ‘at.’

Based on the parents’ genetics, the following coat color combinations are possible:

  • 100% chance for E/E Normal Extension on the E Locus - K and A Loci determine the expression and pattern of black pigment

  • 50% chance for KB/ky Dominant Black (Black Phase) on the K Locus

    • 50% chance for Arctic Type Sable to be “hidden under” the black phase on the A Locus (KB/ky Ay/at)

    • 50% chance for wild-type Wolf Grey to be “hidden under” the black phase on the A Locus (KB/ky at/at)

  • 50% chance for non-black (ky/ky) - the A Locus determines coat color instead:

    • 50% chance for non-black puppies to be Arctic Type Sable coat color (ky/ky Ay/at)

    • 50% chance for non-black puppies to be the wild-type Wolf Grey coat color (ky/ky at/at)

  • 100% chance for S/S on the S Locus - no White Spotting is expected, only small residual white spots (white tipped toes, white chest star)

Dominant Black (KB/_) puppies are expected to show some degree of agouti banding on their guard hairs. This is essentially “leakage” of the A Locus through the overlay of dominant black pigment. Genn is a black phase with visible agouti banding on his guard hairs. Genn and Syl’s black phase puppies will almost certainly have this trait, as well. We do not expect any puppies to have a “solid black” coat color with no signs of agouti banding.

Genn is slowly phasing whiter with each passing year, as are Syl’s black phase sire and all of her black phase siblings. Genn and Syl’s black phase puppies are expected to phase to become mostly-white with age, as well. Several of Genn’s Wolf Grey relatives have also shown signs of phasing to a lighter grey/white with age, so it’s possible that, if any Wolf Grey colored puppies are born, they could phase lighter with age, too.

Regarding Hormones…

As high contents with around 95% Grey Wolf DNA, these puppies will have an identical breeding season to pure wolves once they sexually mature. This means they will only be fertile during a specific period of time each year. Females experience estrus once a year between the months of late January through early March, and males experience a slow increase in sperm production throughout winter, with peak fertility in late January through early March, before semen production drops off sharply again to practically zero for the rest of the year. Outside of these months, wolves and high content wolfdogs are not fertile and cannot reproduce. Females will not ovulate, and the testes for males actually physically shrink to roughly the size of small grapes, since no sperm is being produced at that time.

The breeding season for wolves and high content wolfdogs brings with it a massive surge of sex hormones (over 2,000% increase in testosterone for males!) to stimulate ovulation and trigger the start of spermatogenesis for the season (the production of sperm). This hormonal influx also triggers very intense instinctual resource guarding and breeding behaviors of courtship and strong bonding between mates. It is very common and normal for seasonally fertile animals to experience sometimes significant mood shifts and become much more easily overstimulated in the months leading up to, during, and for a short period after their breeding season. Expect them to display more intense resource guarding of things they consider important, like food, water, territory/pen space, their chosen mate, and even their favorite people. As the breeding season comes to an end and their sex hormone levels decrease, their behavior gradually returns to “normal” for the rest of the year.

It is very important for owners of high content wolfdogs to understand that this seasonally intensified behavior can quickly escalate to reactivity and aggression if the animal and its needs are mismanaged during this time. It is imperative to be aware of and respect the animal’s needs, emotions, and behaviors during this time of the year. Owners must educate and prepare themselves on how to handle a large, hormonal animal during the breeding season. Knowing safe handling procedures, how to recognize, prevent, and de-escalate tense situations, having secure containment, respecting the animal’s emotions and needs during this time, and finding ways to keep interactions between the owner and high content wolfdog short, sweet, and positive, will go a LONG way towards maintaining the bond of trust and respect between high content and owner.

Spaying and neutering outside of breeding season typically will drastically reduce the intensity of the hormonal and behavioral shift in adult animals during the breeding season. However, it may not eliminate seasonal moodiness/aggression entirely. There are quite a lot of spayed and neutered high content wolfdogs who will still display a marked shift in behavior and reactivity during the breeding season.

We do not encourage our puppies to be spayed or neutered until after they turn 18 months of age, because they need those sex hormones to properly regulate the growth and development of their bones and joints. Performing a pediatric spay/neuter under the age of 18 months will void our Joint Health Guarantee in our ownership contract. It is rare for a high content wolfdog to be sexually mature during their first winter and most owners typically don’t see much of a behavior shift during their high content puppy’s first winter. This means the ideal time to spay/neuter at 18 months will happen in mid-summer, AFTER their skeleton is done growing, but BEFORE their sex hormones kick in for their first mature winter before their 2nd birthday.

Although this litter most likely would not reach sexual maturity until their 2nd or 3rd winter, puppy buyers should still be well educated on respectful and safe handling protocols for high content wolfdogs during their breeding season. Non-confrontational handling and finding fun, creative ways to keep your interactions positive with a seasonally hormonal wolfdog will go a long way towards strengthening your bond of mutual respect and trust, as well as help to avoid potentially damaging your relationship with them during the rest of the year.

Additional Info:

  • This litter is eligible for homes within the continental USA and International homes where high content wolfdogs are legal. The legality of wolfdog ownership for every applicant will be verified during the application process.

  • NO breeding rights will be given for any puppies unless they are being Co-Owned by us, with us as the Breeder sharing 50/50 in all health testing costs and retaining final right of approval on all breeding choices. Responsible breeding is important to us! Please contact us directly for more information about our Co-Ownership program.

  • All puppies from this litter, unless Co-Owned as breeding prospects, will be required to be spayed/neutered between the ages of 18-30 months, to allow for full physical maturation before desexing. Ovary-Sparing Spay/Vasectomy is permitted prior to 18 months of age in order to prevent reproduction while keeping the sex hormones intact for proper growth regulation. We promote responsible containment and separation of intact animals during breeding season.

  • Must have reinforced yard fencing at least 7 feet tall, with effective dig and jump prevention, and an outdoor, wolfdog-proof containment (minimum of 150 sqft) is required to be completed with photo and video proof BEFORE an application can be approved and a puppy reserved. If you need tips on how to build wolfdog-proof containment, or how to reinforce your existing fencing, please contact us and we are happy to provide advice and photo examples.

  • Must have experience with verified (Embarked) mid content wolfdogs or higher OR have extensive experience with primitive dog breeds.
