I adopted 2 long hair chihuahua's at 12 months old during Covid 19 from a private party. They are brothers.These boys only training was going to their crate which they love. They are both not neutered. The clinic has just reopened and there is a long wait. They had no shots and I got them in for those. I absolutely love these 2 little maniacs! They are peeing in the house consistently and it's driving me crazy. They usually do this when I leave the room for even just a minute. They rarely poop inside. I know neutering will help, However, they are now 16 months old and I have a 2 month wait. Any suggestions?
