From Winchester's current home: Winchester is a 9 year old male Australian/American shepherd mix.
Winchester was acquired by my husband as a puppy and we have had him his entire life. He has always grown up with another dog, his brother Remington (not litter or genetically related) is a year older than Winchester. About 6 years ago when I met my husband, I had a dog at the time and we then became a dog house of 3 and have been that way since. While Winchester can live with and does ok around other dogs, he may do best in a home as the only dog. Winchester tries to dominate Remington (steals toys from him, gets jealous when Remi gets attention, urinates on/next to Remi as if to mark on top of his marking, etc.) and competes to be the alpha with our other dog Luna (although her being female has helped this, the dog I had when I met my husband was a male and there was more tension between him and Winchester than exists currently between Luna and Winchester). He has not been around cats, but does chase them in the yard when stays come through so he may do best in a cat-free home. Winchester has been to a dog kennel a couple times when we traveled and the kennel's feedback was that he did well around other dogs and really enjoys play time.
Winchester is amazing at fetch! He gets hyper-focused on the toy/ball and is pretty good at tracking it down after it's been thrown. Best part is, he brings the toy/ball back to you! He doesn't seem overly protective of toys, but he will steal toys from his dog-siblings; he doesn't show aggression when a known human takes a toy from him (same with food, he is not aggressive or protective). He does ok on a leash, pulls a little but otherwise does well. He does well on car rides; at first he is anxious but will quickly calm down and eventually just sleep on the floor. Once the vehicle stops, he will stand up and be alert to changes but otherwise he does great. We have taken him on road trips down to Arizona a couple times (a 15 hour drive) and he has done great. Winchester does have quite a bit of anxiety, and was previously on medication for this but he was recently weaned off in hopes of trying a different medication since he was becoming unresponsive to it. Winchester often paces and pants, and anytime something moves or makes a sound he has to stand up and struggles to "chill", even routine day-to-day. Aside from the anxiety, he does have a bit of prey drive and likes to chase bunnies or cats that may come across the yard. He will also dig at the fence line if something is on the other side of it, like our neighbor's dogs. When people come over to our home, he barks a lot for several minutes and eventually calms down. The other two dogs don't bark much at all. Even when we come home, Winchester will bark (just not as intensely compared to a "stranger" or less frequent visitor coming into the home). He will jump up and lean up on you, but he is not forceful enough to knock you down or throw you off balance (I think it's more or a greeting or inspection-like inquiry); if you tell him down he will respond eventually. He does know some commands like sit and come, but is more stubborn when it comes to stay, lay down, or go (away); you may have to repeat yourself several times for him to listen to those commands. He's decently food-motivated but can sometimes be picky/selective. Normally he eats dry kibble and free-feeds. He does shed moderately, noticeably more than Remi (who is a purebred Aussie) and Luna (purebred French Bulldog); we think the shedding may be due to Winchester being a mixed breed. We did a DNA test on him years ago to see what his composition is. I have included the report below, but he is majority Aussie/American Shepherd.
Overall Winchester is a decent dog. The reason we are looking to rehome him is because my husband and I are struggling to trust him around our 1-year old daughter. As she becomes more involved in her world (and the dogs), he makes us nervous concerning potential aggression. When our daughter reaches out for him and pets him, or tries to lean up against him, most of the time he just tries to get out of her way and get away from her. But we have seen several instances where he will turn towards her, snarl and growl. The reason my husband and I are concerned that this could be a problem is because Winchester has tried to nip and bite at me when I have groomed him and he has bitten someone once before (a family member came to our home, the dog was between the doorway and my husband, and we think Winchester was acting protective of my husband). Winchester's anxiety has made it so that we don't feel confident we could take the dog to a groomer, so he has always been groomed at home by us. Winchester does not like to stay still during grooming and pants excessively. In the times he has attempted to nip me during grooming, I think it's from stress and anxiety due to being told to stand still and such for extended periods of time. My husband struggles with grooming as well, but Winchester has not shown attempts to nip at him during grooming. Nonetheless, we don't feel we can trust Winchester around our child alone/unsupervised, and I am currently pregnant and we are expecting baby #2 in July. We are also working on a couple of extensive home improvement projects (renovating a bathroom, then part of our living room, and eventually finishing our basement), which also adds additional stress to his environment. Given the changing dynamic of our household, we feel it may be best for Winchster to find a new home. We don't know how Winchester would do in a home with older children (say maybe 10 years old), and our current child is his only experience with a child to date.
