We have a 12 week old male pom, took delivery 1 week ago.  He is very loose and are feeding him beta complete (chicken&Rice) which the breeder had been doing.  We have given him bottled water in case the cchange of water had upset his tummy and on the vet's advice temp for 48 hours changed to a light diet of hard boiled egg, chicken.  He would not eat fish or rice.  We are also having difiiculty in getting him to use the yard as toilet.  We purchased puppy spray and also dog nappies to hget him used to the smell but cannot get him to clean himself anywhere but the kitchen.  Any advise please?
