Since we planned on spaying Mischa I never got the fancy stuff. I know
@Archer has some pretty nifty dog panties for her girls!! I used a pair of my son's underwear. Put them on backwards, so her tail stuck out that little hole thing that boys underwear has, it worked perfectly! We had also tried baby diapers (cheaper) and just cut a hole for her tail. But she was too wide even for the large diapers, the tabs wouldn't stay stuck. A pull up might have worked better, since they are bigger than diapers! I liked the underwear since it was reusable.
That's pretty smart thinking,using the boy underwear.
And, I did use the pull ups on Daisy. I simply cut a small hole for her nub.
I had a couple of pairs of underwear I put on over the pull ups also with a hole cut for the nub.
She was an active girl, so I fashioned a pair of men's suspenders with clips to keep them in place.
A handy side effect of having all girls around, banana clips! Used one on the top side of the suspenders to keep the straps up on her back and not spreading around her rib cage.
To the OP, that all sounds like a bit of effort, huh?
But I was willing to do it, and did for most of 6 seasons.
I would avoid the spay till after at least 16 months of age to let her body develop.
I can also attest to the spay incontinence issues. After the spay she had leakage upon trying to get up from a laying position.
It is treatable with meds, but the meds, any meds IMO is just taxing other organs in the body.
It's worth saying many get spayed with no post op issues, just know it is a possibility.
Boys and girls-apples and oranges.
@Archer words about a leggy boy from early neuter.
I have a Rocky that fits that description, fortunately and thankfully without any ACL surgeries (knock on wood).
