My chihuahua is 4 years old. Within the last three days her personality has changed dramatically, she walks around very mopey. She has been pacing and never seems to relax. She used to be very happy and I am worried that she is depressed because we bought a new kitten about a month ago. She acts like she is in physical pain, but when I took her to the vet she stops acting this way. I think she is depressed, what can I do to cheer her up?
Thank you.
Ryan
