As everyone knows my son has he and his wife's dog. Barney is a great dog and I've got concerns about his health as this dog has had nothing shot wise but his rabies shot and is not on any kind of heartworm preventative. I've told my son I'd take him to my vet I used and get him checked for heartworms and on preventative and get his shots he needs. He told me in no uncertain terms that the dog is not mine to do with what I want, never mind I keep him all day 4 to 5 days a week, and belongs to he and his wife, not me, and that he has been dewormed. I said maybe so, but that does not take care of heartworms which can result from a infected mosquito. If it is a money issue I can take care of that, I told him I would pay for it. And around my house the mosquitoes are horrible due to the lake by us. We are always killing mosquitoes in here. And I have to take him outside, and am fearful of keeping him out long due to that fact. I spray him with Backwoods Cutter when I take him out, and that is just long enough to use the bathroom. I would hate for this dog's life to be cut short at 2 years old due to heartworms. Anybody, got any suggestions?
