Our girls are so good and tolerant about whatever comes their way.
Bathtime in the kitchen sink is "normal" to them.
They get bathed at least every other week. Sometimes more often.

If I hold her up in the air with one hand and rinse her off with the sink spray hose in my other hand, Bella (above) will do a midair "doggy paddle". She definitely prefers to keep all four of her feet touching something solid when being hosed down. Nevertheless, she is calmly accepting of whatever way I bathe her.

Each of our 3 girls have their own personalities. Bella is our only one to ever do a doggy paddle as described above. Meanwhile, all 3 are super easy to groom. Thank goodness. A clean dog (of any size) is much more pleasant to live with than one that goes a long time between baths.

Here is tiny Bailey also getting a bath: https://pbase.com/britestar/image/174669680
She was next in the sink after I had finished giving Bella her above bath.
Then, Chile got her turn.
