I recently went the same route and added a boy (Brando - also a retired show dog) as playmate to Ruby. If it goes anything like it has gone at my house, you are in for a blast and so is Ziggy.
There's one that comes to our dog park named Rocket and he's very fast and focused on retrieving. I have yet to see him play with the other dogs. He's never mean or anything just not interested in play.
I'm afraid If I do decide to get another I won't have a chance to introduce them beforehand as it Will probably be a puppy I bring from the US.. I doubt there will be a problem since she will be a young puppy…
I still get alot of people who ask what breed zoe is. At least at 8 months no one asks if she is a chi anymore. Some start out asking what kind of mix she is. Every once in awhile someone recognizes that she is a basenji. Just yesterday we were waiting outside a sheetz gas station when a woman looked up and saw zoe at the window with me and had to come over to ask if she was a B.
I get people who uncurl her tail all the time luckily she doesnt mind in the least you can touch her all over no problem. And most of the time she loves the attention. I swear if someone passes by her without petting and adoring her she will look at them like they are idiots.
I think a nice long walk does help with car anxiety. It allows them the time to "do their thing: and everyone knows an exercised B is a calmer B….the only other article I once read offered advice on giving a small bit of ice cream to settle their belly. Most dogs do not do well with ice cream but they do make ice cream for dogs (Frosty Paws) and you could try that I suppose. Perhaps if the car ride was associated with "good times" it might lessen the anxiety a little. Like any species, if your B really has motion sickeness all you can do is to try and be alert to it and maintain hydration. It's good you are aware and I'm sure you will take care. My best to you and your Chance. M
