I am unsure since I adopted him from a rescue group. The rescue group said about 5 yrs. my vet said maybe 10 yrs.
He was neutered by the rescue group in the last 5 months.
I have not heard anything about the blood test.
He does cough about one or two time daily.
He is very active, running around the yard at break neck speed when I come home from work. After we have supper then he sleeps while I watch TV. He has high energy when I am outside with him. Inside he usually sleeps. He was tested for heart worms and given meds at the rescue. I keep him on heartguard monthly. His weight is 13lbs just right. He has a great appetite, he loves to eat. I have never seen him sit while eating. I have nto noticed him coughing when drinking on any regular basis.
