So sorry to hear about your girlfriends dog's aggression. I don't really have any advice on how to handle aggressions but I do know that you should reward the dog with treats for any positive behavior (i.e., if he pees outside give him a treat).
As for the marking around your house, if you haven't done so already it might be a good idea to pick-up Nature's Miracle Stain and Odor Remover to remove all the pee stains/smell. Usual household cleaning products may remove the stain but not the odor.
In addition, you might want to pick up a few belly bands to prevent him from any future marking. One of our YT member '2parises' sells belly bands for a very reasonable price and they work wonders.
Last but not the least, when you're not home you might want to confine him to the bathroom or kitchen until he fully potty re-trained again. |
