Another tip, next time you call the vet, I would leave a message for the vet to call you back when he has a minute. Despite the helpful advice given by the vet tech, I would prefer to talk directly with the vet.
I would ask him to fit you in that day or let him know that you may go to the emergency clinic if he can’t accommodate your request…
As the vet will confirm, without further diagnostic testing and examination there is no way to tell what is going on with the dog.
