Hello, my dog Panda was unattended and my mum was supposed to watch that he didn’t get to my guinea pigs but failed - Morgan is fine but Panda was chasing Bumble. Bumble got terrified, naturally, both my mum and I searched him for injuries but he seems to have no visible damage, although the black part of his fur is a bit wet and when he scratched his side, he lost a little tuft of fur that also felt damp. Now he’s lying on his side and chin which he NEVER typically does and won’t even touch food while Morgan is enthusiastically eating. What do I do? Is this just shock? Doesn’t he need to see a vet?
