i was really worried about taking my new basenji to the dog park this past weekend, because his last owner said he was bad with other dogs, but he had so much fun! i'm proud of him! he even got a girlfriend (and boyfriend!!) (this gorgeous rosey light fawn-greyish colored italian greyhound - absolutely beautiful!) and then this grey male i.g. started humping him, lol.. that's the boyfriend :p . so good job to your basenji! it's so nice to see them get along with others!
In the mean time, you can probably smear some plain yogurt on her itchy spots. At least you won't have to worry about them getting licked off. Yeast infections are difficult to treat because the yeast produces spores that are difficult to erradicate completely. Antibiotic and steroid use makes it worse.
