The Question
“Hi Dr. Paola,
My shorty Jack Russell Terrier gets anal glands that itch, which leads to a vet visit every 2-3 weeks. She’s 8 years old and has a healthy diet plus vitamins. I’ve tried Glandx, which doesn’t work. We tried pumpkin for more fiber, but still the same results. Any suggestions you may offer my girl? Thank you," - Stella
Quick Info
Hi Stella,
I can hear how frustrating this is, especially when you are already doing the right things. When anal glands are filling and causing irritation every couple of weeks, it usually means the issue is not just fiber, but how the glands are emptying or what is affecting the anal sac environment. In many dogs, especially smaller breeds like Jack Russell Terriers, the ducts can be narrow or inefficient, so even with good stool quality, they do not empty properly. On top of that, underlying inflammation from allergies, most commonly environmental or dietary, can increase gland secretions and make them thicker, almost like trying to squeeze toothpaste through a partially blocked tube.
Since fiber supplements and general diet adjustments have not helped, the next step is to look a bit deeper. A targeted diet trial using a hydrolyzed or novel protein veterinary diet for 6 to 8 weeks can help determine if food sensitivity is contributing, even in dogs that seem otherwise healthy. At the same time, your veterinarian may consider evaluating the gland contents for infection or abnormal cells, because chronic impaction can sometimes lead to low-grade infection that keeps the cycle going. Some dogs also benefit from adding specific types of fiber like psyllium rather than pumpkin, as it forms a more consistent stool that can apply better pressure to the glands during defecation.
If this pattern continues despite these steps, there are additional options that are very effective. Regularly scheduled expressions before discomfort starts can help break the cycle, and in recurrent cases, procedures like anal sac flushing or infusion with medication can reduce inflammation and recurrence. As a last resort, surgical removal is considered, but only when all medical options have been exhausted, since it carries its own risks. In a situation like this, a complete review of her full history and fine-tuning the plan is important, so you are not just reacting every few weeks but actually getting ahead of the problem.
I hope this helps!
