We have a 4 year old adopted rescue beagle who is about to start his serious heart worm treatment. He is now strong and really rambunctious. On one hand, I'm hoping that will give him a better chance of survival. On the other, how do I keep him calm? He is not neutered, since that is yet another thing the vet recommended we hold off on until after the treatment. He is highly allergic to grass and despite my efforts to make him a house dog, he loves to escape. Any thoughts or advice from someone who has been through this would be greatly appreciated. He's a spoiled mess, but we love him.
