Why do my dog's anal glands fill so fast and need weekly expression?
I have seen a few dogs like Bella. Many times there will be an underlying cause such as allergies that cause this but not always. I would recommend a food trial with a prescription diet made by Royal Canin called Ultamino. You will feed her ONLY this diet for 2 months. She cannot eat ANYTHING else, no treats, bread crusts...absolutely nothing. At the end of the food trial, if her anal glands are not bothering her, then you know its a food allergy. If they are still bothering her, then its not a food allergy. If you haven't tried this yet, its worthwhile. Sometimes a short dose of anti-inflammatory or steroids can also help wth residual inflammation. Her doctor can prescribe these medications if they seem warranted. Best of luck with Bella!
