What motion is observed in a horse once the ischial arch is passed with a urinary catheter?

Any ideas?
PilotLPTM [1.2K]

I'll choose Golden Retrievers:

These dogs where created for duck-hunters. Their purpose was to go catch the ducks that fell on the lake/river once they were shot by the hunter - here we see how they serve (or actually served) men.

Nowadays, Golden Retrievers are known to like water a lot, and to be very playful with it - and here is where we see a genetic adaptation. They needed to be in water, and were modified to like it.

Hope it helped,
