Hi Stephanie, welcome and welcome to the breed.

I had a spinal injury a few years ago and the surgeon warned me of permanent nerve damage causing incontinence being a potential consequence if it got worse. It's called "cauda equina syndrome", I did a quick search and it looks like it occurs in dogs too. Essentially you lose all nerve feeling on your bowel, hence not knowing when you need to go. I'm not sure what the solution is (if any) but it could be a clue.

Did she always have them or did they start after something/some time? Do antihistamines clear the problem?

Ah yeah though the site that I saw clearly had a picture of a Basenji representing the breed! Your link, they look nothing like Bs

My condolences, a good long life

Just seen this breed on a somewhat strange site, is it a thing?

Nice, they are about in a few different adverts, I spot them every now and again.

OMG, nooooo! She's so good now, it's not time for terrible twos! I have noticed that she does need to be told multiple times to do things nowadays but she's very well behaved in general, we have a good understanding going on.
Thanks for the warning!

Safi had her 2nd birthday yesterday, time is really flying!

In addition to what Elbrant said, you could try valerian or st john's wort for calming. You could also try desensitising him, drive to the vet a few times (if it's practical) but don't go in, give him a reward for staying calm etc. I'd personally avoid pharmaceuticals.

I don't get other dogs in the yard but I do get foxes, she will sniff but isn't bothered.

My B won't pee or poo on my property at all or even in the vicinity, I have to take her for a walk down the road to get her to go. It started around the same sort of time, before that she used to go in the garden or drive no problem.

It was actually based off this photo. I got the AI to describe the photo, then I got it to generate a new image based on its desciption:

Thought you might enjoy these, the first one was created with Adobe Firefly, the others with MidJourney, the first three are generic Basenji the last two are based on Safi:

@elbrant Yes, she's good an patient sometimes, I've been taking pics of her from day 1 so she's used to it, I'm allowed a couple of mins and no more though.

A fine looking Basenji!

Ah ok cool thanks, I had something like that when Safi was smaller and it was the most successful for sure. She outgrew it quite quickly though

What does it look like?
