She’s urinating as usual but she is going to the vet’s in a few hours so I can ask about a UTI.

Could it be excitement from play time?

it’s very possible she’s overly excited, but i think it’s always best to rule out a UTI in cases of incontinence in bitch puppies. they seem to be prone to them when young. in fact, the only time mine urinated in her crate, she had a UTI.

good luck. 🙂

Have both of these dogs been neutered? (I assume they are male).  If they aren’t, get them to a vet now.  Mounting is all about who is in control — not about sex.  But, having all those hormones in their bodies amps up all reactions.  

If you are making a fuss, and there is snapping and barking involved it sounds to me that the humans are not the ones in control in your life.  Both you and your boyfriend need to start working with your dogs on the basics such as down stay, sit stay, go to your bed, bring me a toy, find the ball, heel, etc.  As you gain control over the mind of your dogs you show them that humans are the ones in control and they will feel less need to show dominance to each other.  It wouldn’t hurt to find a trainer to help the four of you!

Along with this work to calm your dogs with strong leadership, your best tool might be a loaded water gun, or spray bottle.  No yelling.  No whistle.  No scolding.  Just pick up the gun/bottle and spray the mounting dog in the face.  When he dismounts he needs to be redirected: “find your ball”, “go to bed”, “bring me your toy” or “go outside” (this is why you need to teach these types of commands to your dog).  The water needs to happen so fast, and with no fanfare — it works best if the dog never figures out that YOU are the one making the water happen. Keep the guns/bottles all over the house so you can get to one in a step or two. Don’t try to drown the mounting dog, it is just on shot to his head/face to startle him and break his focus on dominating the younger dog.  It sets up the association in his mind that when he dominates the other dog, this uncomfortable and startling thing happens.  The the redirection to a toy or bed channels his mind in a better activity.

Scolding, blowing whistles, and shouting escalate the excitement — you are barking along with them in the mind of a dog.  Stop.  Be calm.  Calm, positive energy, and 15 mins of focused training 2 times per day (at least) is what is needed to improve the situation. 

Good luck.

Maybe it has water in the ears, which can cause the equilibrium to be off.
