I need advise. My english bulldog is 3 yrs old and will not eat and barely drink. He started with kennel cough and the vet but him on an antibiotic that hurt his stomach. Took him off that and he has become very gloomy and just will not do anything. I took him to the vet this morning and he acted fine. I get him home and he is right back into the dead dog act of not eating, drinking, or moving. Any suggestions? I think it could be all of the medicines they have put him on, or maybe depressed. I am really worried about him getting dehydrated. Help!!
