I'm a little late responding --
Daisy has to have hers emptied every 2 - 3 weeks. I hadn't heard the thing about "creating a cycle" before, but I only do it when she's scooting, so I don't think I'm doing it too much. I do hers in the bathtub, then I give her a bath, then I clean the bathtub. It is GROSS!
It took me a while to get "good" at it, but it's pretty easy now. She used to absolutely HATE it and I was so dense I couldn't figure out why. Then I realized -- long nails, bad. Poor puppy. (Man, like the last 3 things I've posted have all been about me inadvertently injuring my dog. She's going to have a lot to talk about in therapy.) Also, my vet uses a paper towel to "catch" the butt juice, but I'm not skilled enough to find the glands when I have a paper towel in my hand. I just wear latex gloves (and put cotton balls at the end of the finger tips so I'm not digging my nails into her poor butt) and make sure her butt isn't pointed toward my face
She leaks sometimes. It's gross. Everything about it is gross. It seems to only happen on my white quilt (which I guess is better than the sofa -- easier to wash).
Supposedly increasing their fiber (to make the stools firmer) is supposed to help. Also, avoiding foods that claim to "reduce the amount of waste," like Nutro. (I almost had to step outside with the Nutro rep at Petsmart. She's really condescending and when she started in on the "makes less waste" argument, I just wanted to slap her. She'll follow you around the store, too, if you let her.) I switched Daisy to diet food because it is higher in fiber and that seemed to help, but then I had to change her food again because of a potential food allergy. My vet recommended canned pumpkin (like you buy for making pumpkin pie), but she wouldn't eat it.
Okay, I'm going to shut up now. That was really long.
