Jack is a loyal and in the past energetic dog. He is 12 1/2 years old and this year has slowed down to the point he was no longer interested in anything, was hard to get up and paced at night. He has numerous lumps and hates going to the vet (we had to put him under for his last shots last year, so at his age i am not prepared to subject him to the stress. Since taking your biscuits the improvement was unbelievable within 48 hrs. He is now taking an interest, is calm and sleeps through the night. We walk every day and is once again always at the door to greet me with tail wagging.
