HELP!? my dog came in the house with skin and white fur in his mouth :(?

It could have been many things, such as a rabbit, or even a cat. And any one of those creatures could have been diseased. Make sure he's up to date on his vaccinations. If you have seen rats around, or know of people laying poison, you should phone your vet immediately.

I think it was a rabbit, but it could have been a lot of things, it could have been a cat or maybe a smaller dog, such as a white chihuahua. But any animal that he could have encounter could have been diseased, i'de call your'e vet and have him checked, but he might have just had a good snack :P

It's unlikely that the animal had anything that would kill your pet, but it may have just get a little sick.

Well I wouldn't just be concerned for your dog, take him to the vet and make sure he has all his shots and didn't contract anything, but also if it was a cat, you're going to hear from an angry neighbor possibly.

yes you should be worried. take him to the vet to make sure he isn't poisoned.

the vet should tell you what to do from their. you need to take him to the vet ASAP.

he might get a deadly parasite or something like that! maybe even rabies....or a worm.

take him to the vet!

if it was small it was prob a mouse and that could carry lots of different disease and if its big it could be a rat or a rabbit
