I don't know how old Toby is? All I can say is that you know your own dog and usually we just know when something is really up with them? Maybe he picked up something that he shouldn't have eaten on a walk or in the garden? Yorkies are very bad at doing that!! If he's the same 2moro, I would take him to the vet and see what he says.. he'll find out nif he has a temperature etc.. hugs to Toby! Ana xx
