before you read / respond, i am not happy or joking about posting this - help, it hurts so much to see my 13 yo dog suffer.... he is sick, has lots of lumps on his belly / side, "coughs" a lot and is slow to move...while his appetite is normal, there are days he does not eat. although he has good days, i feel he is suffering more and more. i need to find a humane way to put him down... we live in rural maine, vets are not close and even if they were, we do not have the $$ / reliable car to try to drive the distance. i have access to guns but do not have the experience and really cannot bring myself to try to shoot my friend and "miss a little". the only thing i can think of is that i can get a hold of some valium / pain pills....if i crush them up and put in food, would it just put him to sleep or would there be suffering? he is about 65 lbs... how many milligrams would i need? is there another way to try to help him out?
