I have just bought 2 male chins who are about 3months old. The bigger of them does not seem to be eating anything. He is fairly tame and is happy to be picked up but when I put him back and offer him a treat he just starts barking. My other chin started eating straight away although is not so happy about being handled. I am worried about the one that is not eating. Is it cos he is still adjusting to a new enviroment or is it a male thing. In the past I have had only female chins, one of which only barked when we were waiting to see the vet.
