Good luck! Do report back, if you think about it? We see hypothyroidism leading to hair loss in Dobes, but it doesn’t usually come with rashiness. I’d be very curious about any other vet’s ideas about it.

oh wow, apologies for the crazy number of responses. sometimes this site glitches in the strangest ways.

That’s possible, too. I certainly wouldn’t rule out a second opinion. I’d also look for a veterinary dermatologist, if there’s one near you.

I would wonder if there’s an allergy situation going on in addition to hypothyroid.

I agree with Dr. M – wobblers or a disc issue would be my immediate concerns.

You really need to get an obedience trainer involved if you’re unable to handle this puppy. He doesn’t know what “no” means. He’s a BABY and needs you to teach him how to behave. ALL puppies are bitey, ALL puppies need training. Dumping him and getting another won’t fix the issue.

DO NOT get a second dog until this one is at least 2 (trust me on this). You need to focus on his obedience training before bringing a second dog in, plus littermate aggression is a very real issue you don’t want to deal with. Instead, focus on obedience training with this little guy. Avoid Petsmart – find a good group class with a balanced trainer. At his age, he could benefit from puppy kindergarten, as well. Look for a training company which provides both.

I agree with Sarah – get a box with higher sides. You should have 4 for that number of cats, anyway, so it’s a good time to pick that up.

In addition to the suggestions already give him, he should not have free access to the house. Leash him to you or confine him to the room you’re occupying, and take him out every 30 minutes. Once you’ve cleared him of any kidney or urinary issues, you’ll know whether this is health or training…if it proves to be training, you’ll want to SLOWLY increase time between visits outside. I would never restrict water unless you had a gulper.

Could be anal glands, could be diarrhea, could be worms. I wouldn’t consider this emergent, but if it persists I’d give the vet a call.
