I plan on asking my vet first, if I can treat for fleas and ticks while treating for heartworms. It is a big worry that he might get sick with something else while fighting heartworms, as we are due for more than one monthly treatment of Immiticide. Later this month he goes in for two more shots, and we have another month, atleast, of being slow and lazy while the worms breakdown and pass throuh his system. His appetite is up and down, which is expected, but I dont want anything else to tax him if I can prevent it. Even a natural alternative (working!!) repellent would be helpful really.
