Raven gets his last heartworm treatment on the 12th. Unfortunately the treatment has made him more aggressive. We are going to a behavorist and will have the last treatment paid by us. He was friendly to all people the first couple months when I picked him up in September but now has jealousy issues with anyone but his main owner. He does not fit with our lifestyle. He is a goofball,very smart(picks up tricks quickly) and is as sweet as can be when off the steroids. He knows sit, stay, lie down, and wait. He always goes to the bathroom in the same spotoutside or asks to go out to his pen for potty by going to the door. I picked up this dog as a backpacking, camping and road partner but after much consideration, he needs a family that has less visitors. Off the medicine he loved every person who walked through the door and had met about 40 people before the aggression started. He has been friendly to most dogs except for the dog that lives with him. He loves chew toys.He doesn't seem to have any separation anxiety.
