So we just got back from the vet with Bentley....... He had to go in for a recheck on his heartworm treatment & get some more meds for the treatment. The vet said his heart sounds good & his hair is growing back good (hard for me to notice since I see him everyday). We go back on August 4th for hopefully his last round of treatment-by the way his treatment is a slow kill of the worms instead of theosed nasty painful shots. She also gave him pretizone for his itching I hope that will give him some relief. He was very aggressive though & try to go after a pug in the waiting room. Since he has been feeling better after rescuing from the pound he has been aggressive he is fine with my beagle/basset mix but I want to bring him to some playgroups but I'm afraid he will just be a terror to the other dogs. I have had him around a friends dog was and he would follow her around & then snip & growl at her. Any ideas of how to fix the aggression in him.......
