Hi Folks, I have an 18month old long hair miniature chihuahua and I'm wondering what's going on with him. Ever since thanksgiving he has not eaten any of his regular food or treats to the best of my knowledge. He has drank a small amt of water but when I give him his treats or put out dry food he smells it but doesn't eat. Is it unusual for these breeds to not eat for a day or two? He is alert cool dry nose but slow to react to us here at home.
