Yep, they can hold a grudge sometimes after a bath, grooming or the dreaded nail trim. I have the tools needed to groom. I used to lay a beach towel in the tub to do it. It kept them enclosed and made it easy to clean up the mess. Now I can not get up and down that easily or bend over for long. Makes it next to impossible to do it all at one time, so I do it in stages like you. I do like to take them twice a year to the professional groomer.
