Give him benadryl, he may be having a reaction to the lepto shot. Call the vet and ask for dosage for his size. My yorkie Teddie had the lepto shot when he was still with the breeder, and he had a slight reaction. No eating and dry heaves. Please contact the vet and take him in, and ensure they document this as a possible side effect so he doesn't get the shot again if that is indeed what his symptoms stem from. Good luck...
