bladder infection or acting out?
 

I have a two year old yorkie who has recently been trained to use the restroom outside. I keep him in a crate during the day and have been for the past month. He stays in there for approximately 4-8 hours at a time. Up until now, he's been doing great.

We recently decided to adopt a new yorkie puppy. He's of course had his share of accidents, but is doing well with training. My 2 year old seemed angry at first but has started to warm up to him.

I had already taken my 2 year old yorkie outside several times the other day when I noticed him peeing by the door. He had just been out an hour prior. Yesterday morning he woke me up needing to use the restroom and when I sat him on the floor he began to pee immediately, which is unlike him. I took him outside where he continued to pee a lot.

I've made sure to stay home as much as I can to let him out more frequently. I left for an eye doctor appointment today and was gone for 2-4 hours and when I came back, he had peed in his crate. He's never peed in his crate before. I did put the new puppy in his crate for a couple of hours, the day before, while I took my 2 year old to the vet (which he peed in, but I wiped it up) My two year old has even begun to pee less and less when I take him out, and seems to not have the urge.

I'm just concerned and am wondering if anyone could give me any advice. I don't know if the new puppy is confusing him, he's acting out because of the new puppy, or if he has a bladder infection. Any advice would be much appreciated!!

Only a vet can diagnose a UTI, and he'll need antibiotics to treat it no OTC treatment for dogs on it.

I'd not say this is behavior as marking is behavior not peeing in one's own crate.

Sounds like something is going on.
