I recently brought home a 6wk female puppy (Bella) & i notice right away my 1 yr old male dog (Puffin) is now peeing all over my house. Just a week a go Puffin had an ear infection the vet told me he recommend for him to be kept inside the house. He slept w/ me on my bed all of last week & during the day he would stay home w/ my mom & my 2yr old nephew. My mom told me that he would have one accident a day. But ever since this sunday when Bella came home it got worse, i'll take him out to pee & less than an hour after he comes back in the house i'll find a puddle. Right now Bella is getting most of my attention could this have something to do w/ it? Is he just marking his territory? Is this normal behavior? How can i resolve this? I really don't have much experience w/ dogs i've been a dog lover all my life but Puffin was my actual first dog. The reason I decided to get Bella was so Puffin could have someone to keep him company when ever he's home alone.
