My dog has been not himself for almost a week his mouth is very dry he is barely drinking but does poop and pee 2ce a day sometimes once he is a chihuahua 6 years old what's is wrong with him ? He keeps swallowing but his mouth is dry and his breathe has a smell to it

Could be internal organs!

Go to the vet.

Really really hard to diagnose from your description. Your pet is not elderly and I don't recognize the symptom of dry mouth (as it appears to you, maybe not be to him). Sounds like he is not dehydrated if he is evacuating normally, but would have to say only avenue open to finding out what is wrong is a trip to the vet.

Sorry, but nothing appears familiar to me; maybe to another dog expert here it may, but I think they will tell you the same... to the vet he/she goes.
