Wow, another "funny you should mention this". Because we took my dad's dog today to have this done. I've mentioned 100 times, she's not REALLY his. I got her from the pound, dumped her off, my sis was suppose to take her back to Ca, blah, blah, blah, LOL.
Anyways, my sis was here last wk, and said Sophie's glands were REALLY hard. She tried to express them (how she knows about this..I have no clue) Well, she'd just been in to get her nails trimmed and a cyst drained so they didn't want to take her in again the same wk.
Sooo..Dad and I took her today. ACK!! That's just the nastiest stuff, EVER. The smell, the sight, the HORROR of her howling and crying and the vet with half his hand up her bum
Guess they were REALLY, REALLY full and hard.
He said they made need done a couple times a month, every few, once a yr, or never again.
Guess you just need to pay attention to things like the dragging of the butt. Bet you could google other signs. I'd do it, but I'm still sick from this morning.
