I have a 7 month old chihuahua male named cheeko and he has been acting really strange. It started last week when my bf went away for a few days and he had major anxiety and kept crying and walking around the house trying to find him. After he returned, the crying slowed down but now its getting way worse, he does it constantly. He barley ever barks but whines and tries to cry a lot. It almost sounds like grunting sometimes. Does anybody else have a chihuahua that does this??? We just had him at the vet 2 weeks ago and she said he was healthy and fine............... heeeelpp!
