Mimi had anal gland sacculitis not too long ago. She was so uncomfortable & she has a way of letting me know that her anals are bothering her. She kept looking back @ her bum like something was poking her & kept sitting down & standing back up, very restless. She never scoots tho but she licks her behind. I've been expressing them ever since I got her bc she can't express it herself & my vet taught me how to express them externally bc I was taking her in every 2 weeks to get it expressed. This time, the vet had to internally express her glands. 1 was impacted & the stuff that came out was very pasty.

TG there was no infection & she didn't bleed either, maybe I took her in b4 it got that bad. But vet said that her glands were inflamed & they can do laser therapy treatment which has good results. I opted not to bc I didn't know anything about it & it took Mimi 2 days for it to not bother her anymore.
I think a change in diet caused it, specifically the salmon in the kibble (maybe). So I switched them back to their reg kibble & it hasn't happened again. I'm not sure if it was food related or if it was something that accumulated & I was only expressing 1 gland while the other was not getting expressed, causing the impaction.

So now, whenever she goes to the vet, I'll have them check her anal glands too just in case.
Maybe placing a warm towel on her bum area will help for now & you can take her in 1st thing in the morning. I hope she'll be ok!
