“We have two Irish Wolf Hounds. Unfortunately they are brother and sister, I know you aren't suppose to adopt litter mates, but the breeder was not going to bread the female any longer. The pups are Brindle, now that the explanation is over. The reason we went with Sentinel meds for our dogs is the chew on each other so a topical flee medication would make them very sick. Allivet was very efficient about getting the meds out to us in a timely atter. Good Job.”
