Why is my dog biting her butt and struggling to poop? Anal glands?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | spayed | 5 years and 2 months old | 14 lbs

For the past couple weeks I noticed Mollie acting weird, she would act like something was biting her butt, when she runs her back end is sideways and she only poops once a day, you can see she has to go poop but she won't, check her bedding to see if it was worms but didn't see anything. I'm getting really worried and I can't afford a vet at this time. Please help, she's my world!

Hello. She may be having some irritation from her anal sacs/glands. These can become impacted or infected and are itchy or painful. A veterinarian or even some groomers can express these for you. Try calling a grooming center to see if they offer just that service alone to keep your costs low. There may even be instructional videos online to teach you how to do it yourself, but it can be unpleasant and most dogs do not like it.
