Have a ten yr. old Jack Russell male who has started trembling, usually in the evenings - living in a climate which is not usually cold, but has been more than usual lately. He also is sleeping more than usual. Has been vet tested for Addison's and results came back negative. Will possibly be referred to specialist which is not in our budget. Other than above symptoms (sometimes he does not eat as eagerly as usual and is on vet prescribed food) he is usual feisty, full of energy self most of the time. Thank you for any input.
