My little 5 month old puppy is normally a rolly polly, fluffy active little soul. This evening he's not acting himself. He's not walking suddenly, and leans to one side and lifts one of hind legs up, depending on which side he lies against? He will scidder across the floor and sit at my feet, and cries when left alone in the room. He's never acted like this. Can he be having tummy problems? I'm constantly having to check the floors for things as he will try to eat/chew anything and everything. He is able to walk, but he'll try and then put his little bottom to the floor quickly. Does anyone have any advice? The vet won't be in until Monday morning and it's Saturday evening!

Bichon Shi Tzu that is, sorry for the spelling

I would say find an emergency vet that is open. I don't want to panic you, the signs could be of something serious, a virus, worms, etc. But only a vet can determine which. Good luck!
