Are you giving her a treat every time you give her the ointment ? This really helps with Poodle, and even with my kittens , too. Poodle does not like getting a bath, but he knows that if he gets one, or has his toenails trimmed, then he gets bologna afterwards.
I give all the kitties a foot massage every day, as part of their daily petting routine, so when I clip their sharp little toenails with my fingernail clippers, they think it is all part of the massage and are fine with it.
Maybe even just call her out for a treat during the day, and do nothing except give her the treat, and she won’t be sure if she is going to get a treat or ointment?
We used to do that with horses that didn’t want to be caught. I would go out with a horse treat and follow them around until they let me catch them, give them the treat, and walk away.
Pretty soon, they decided it made more sense to let me walk right up to them. I always gave them the treat, but sometimes, i also put the lead rope on and did whatever I was wanting to do.
