Answer
Dear Kay, I am sorry to hear that your friends dog is not well.Getting any pet put down is not a pleasant experience, but you must also look at if he is suffering and struggling to keep alive now. I would recommend a trip to the vets or even a phone call, he may suggest ways to make your friends pet comfortable through medication,or diet change. Your vet will know if your pet is suffering and if it is time now. I know that it is a very difficult situation, but sometimes you have to let go of the ones you love. Your heart will tell you the truth, good luck and keep in touch!
