Jealousy/Anxiety in my male Cocker Spaniel

Question
I have a 2 yr old male cocker spaniel that is definitely hitting his terrible twos.  I have had him since he was weaned, and have never had a housebreaking problem with him except for the puppy bladder/puddles when he gets excited.  He is used to being the only dog, and when we got a male American Bulldog this fall he started behaving very badly.  The cocker is definitely the alpha male; the Bulldog submits to him and is never agressive.  They play together very well, but they both vie for our attention and its obvious the cocker doesn't like the sharing of affection, toys, etc.  He has started peeing in his bed, on toys, doors, and on my spot in the bed and my clothes. He has also started shaking and leaving puddles of pee every time we go to put his leash on him, tell him no, etc.  I have an appt to get him neutered but the vet said since it's a jealousy/anxiety thing that it probably wouldn't help. It might help you to know that I moved from the house he has grown up in to my girlfriend's house over the summer, so he's also in fairly new surroundings.  Any advice?

Answer
If he's two and is still having "nervous piddling" - and from what you're describing, the very first thing I'd do is check him for a UTI (Urinary tract infection).  Dogs do NOT pee on their own bed.  If you can, get a first morning sample in a sterile container and zip it in to your vet right away (if you can't, refrigerate it).

Yes I'd certainly get him neutered for a whole lot of reasons but mainly because it prevents a couple of cancers later in life.

I'm just re-reading your question and thinking - there's something amiss here.  One dog is always the alpha dog but if that's cool with your Bulldog then there is no "relationship" problem.  And the shaking/puddles thing is bothering me.  So I'd most definitely get him a total Wellness check (bloodwork, etc) and, for sure, a urinalysis...and ask for a culture too.

Anytime there's a significant behavioral change it's best to rule out a physical cause first.
He could have a UTI or a bladder infection - get it checked out.  The fairly new surroundings don't account for this - 'nor the new Bulldog (especially since they play well together).

If he wasn't an anxious dog to start with (was he?) then I'd very much doubt he's suddenly become anxious.  So please get a total checkup and a urinalysis before you get him in for neutering.

If that all checks out and there is no physical problem, then write me again and we'll tackle the behavior.  But I'm strongly suspecting he has a medical issue.  Easy test - easy solution
if that's the case.

If it isn't - I'll have a ton of questions but this can be solved.
