I gave Belle a bath today but I'm having issues getting her tail pocket clean. It isn't very deep but every time I touch near it she clamps her tail down really hard. It makes it almost impossible to access. Is there a trick to get them to relax? I did get it clean by going very gently and distracting her with treats and it wasn't very dirty so I know it's not infected. I was just wondering if there was a trick to get them to stop clamping their tail down for cleanings? I don't think her previous owner ever did it...it seems foreign to her.
