I think a lot depends on what dogs learn as wee puppies. Because my Chihuahuas work as professional models (for others; as well as for me), they are trained & have learn to go with the flow. I used to think dressing a dog up was dumb & actually would turn down many of the props I was offered after a pro shoot. But with Bella & the other two girls, wearing outfits now & then seems natural. They actually enjoy it. That's their personality.
Sahraa has a different personality and experienced a totally different puppyhood. So I can understand why she wouldn't tolerate what my 3 little girls seem to enjoy.
