I think my puppy zoey is sick she is acting strange, she is a lab and boxer mix, she is normally super hyper and a bull in a china shop, but since yesterday she wont eat, she is constantly sleeping, she doesnt really want to be petted and she is slow, she has diarrhea and is just not happy looking.she is still drinking water tough luckly. I dont know whether to wait it out and see if it goes away or what, mom said she isnt taking her to the vet til atleast wensday, but will she make it that long? and could there be anyway i could help zoey myself? help me please..she is less than a year old
