Pet's info: Dog | Chihuahua | Female | spayed | 9 years and 10 months old | 11 lbs
My Chihuahua is older 9+ years old, her anus has become darker in color and she's in some discomfort. She has a difficult time pooping and has had problems expressing her anal glass in the past. I haven't seen any blood, but she has been scooting a lot. The soonest vet appt I could get is for 2 days away. Is it possible she has perianal fistula? And will she be ok for 2 days until the vet can see her?

Poor Willow! Some dogs can experience pigment changes over time or with chronic inflammation. It's quite possible that the darkening of Willow's anus is a relatively normal change. As you've mentioned, scooting commonly occurs with full anal glands. I'm glad that you have a vet appointment scheduled for her. Your vet will be able to perform a rectal exam to be sure that everything feels normal, as well as empty her anal glands. It should be ok to wait 2 days since that's the next appointment. Full anal glands certainly aren't an emergency, but sometimes the anal glands can become impacted, infected or rupture, which would be a more urgent problem. If you notice any significant swelling or redness on her hind end, I would try to have her checked out sooner. I suppose that it's possible that she could have a perianal fistula, but these occur most commonly in intact male dogs and are often quite red and oozy. It's far more likely that her anal glands are simply bothering her. I hope that all goes well for Willow!
