Rehoming our family pet. Please read on... We adopted Hippo in 2015 from York County Humane Society. I believe he is purebred pitty, but we do not have any registration to confirm. Hippo was found in great health roaming a parking lot but no family claimed him. He is neutered and knows basic commands (sit, lay down, and occasionally will stay). We have had him since then with an older family pet (female greyhound) and two kids (now 11 and 13). We had cats with him at one point, which he was fine with after some time. Curious at first, but kittens are perfect so they can grow to love him. He also does well with chickens (we free range ours, and he doesn't chase). As most pitties, he thinks he's a little dog and loves lap snuggles and sleeping in bed with his humans. He's isn't a super high energetic dog and sleeps a good bit during the day. He barks very loud when someone is at the door, or if you go outside without him. He has marked inside a few times before, which became a huge problem when we began boarding other dogs, so we've had to use a belly band with him for this. He is not leash trained him as we have a large property and he enjoys to roam. He also LOVES balls and kennels very well. All this being said, Hippo is an amazing family pet, and it truly breaks our hearts to rehome him. Especially for my son with whom he has bonded. Health: Health is perfect. He's 65 pounds of muscle and a happy tail that can whip something fierce. He does NOT like having his nails clipped, so we've been prescribed trazadone and gabapentin for the at-home clippings, which really helps. UTD on all shots/vaccinations and has been consistently on flea and heartworm preventative. Why we're rehoming: Multi-dog incompatibility and aggressively territorial. We have begun running a dogsitting/boarding business out of our home and Hippo is inconsistently compatible with other dogs. He will attack other dogs over food aggression and to protect his family. He does well with non-reactive elderly dogs and puppies after slow introductions. He is dominant, so incompatible with other males. He has randomly gotten along with other adult female dogs, but with slow and safe introductions. We have always muzzled him around other dogs until we read his body language that he is comfortable. Hippo is also territorial of his home; he has taken the opportunity to run out of a door that was not fully closed and superficially bit the forearm of an Amazon delivery person, an error on our part for not fully closing the door, of course, but also can be a liability if this incident happened off our property altogether. Who Hippo would be good with: A home that has no other dogs and with a family that understands pitbull behavior and responsible aggressive-breed ownership.
