Thin Jack Russell
I have a 13.5 year old jack Russell blind with cataracts still chasing cats!! However he has lost a lot of weight over the last year he eats and drinks well but throws up at night regularly. He is generally happy but family and friends have started to ask if he s sick?
Have changed his food to senior dog old with sensitive stomachs and he has 2 small meals a day. Still very thin and being sick but not unhappy and not in pain no obvious lumps or bumps that are visible?
Any thoughts?? Thanks in advance.
