"In order to get along with a Basenji, you have to be at least half as smart as the dog!"
Hair could be an issue as well. I shed when I brush my hair, toss and turn at night, etc. Every once in a while, doodle will ingest a stray strand of hair... when she "eliminates" it, it will often times result in a bit of solids dangling from her backside. It kind of freaks her out. I simply use the ever popular poop bag to assist in removing the dangling solid and any tether to it.
(that was the most polite way I could think of to describe it)
I have seen this with my own dogs from time to time. If any stool is dangling it does seem to upset them, sometimes resulting in frantic spinning to try to get rid of it.
@elbrant - Note that responsible breeders will "pick" the pup that best suits the potential home, not the other way around.
I think this is very wise. I know someone who consistently gets the wrong pup (her breed is GSD, not Basenji) because she thinks she wants a "high drive" dog, and invariably she ends up with something she isn't able to handle. It would be much better if the breeder picked a suitable dog for her, but ego gets in the way for some people and they make bad choices when they are allowed to do so....
I'd like to see more pictures, e.g. side view standing. Colour pattern and head (if you ignore the ears) are suggestive of Basenji. What are her mannerisms? Does she bark? Clean herself like a cat? How is her training coming along? Difficult or stubborn or quirky? Lots of things that could point to Basenji!
Can you be more specific? What problem are you referring to? If Fanconi, it is a genetic recessive and there is now a test for it. Just saying "USA dogs" is a pretty broad generalization.
A lot depends on Lenny, how cooperative he is and how sensitive. I had difficulty with Perry when he needed them. Looks easy at the vet, and the first day was no problem. Second day he saw me coming and was having none of it. Might have been easier if I had had help, and I know some are just fine with it, but he was always a wimp about anything that was uncomfortable. I've done it with cats with success, but put a towel around them to stave off claws and teeth. I just used saline in a syringe at several locations. Tent the skin, inject beneath it. You might inquire about IV fluids. Some vets will send you home with them, some want it done at the clinic.
