This is exactly who this formula was designed for. Surgery removes the lump. It never addressed why your dog's body kept producing them. That root cause — gut dysbiosis leading to immune surveillance failure — is still happening after surgery. CanisPSP™ targets that directly.

Turkey Tail contains compounds called PSP and beta-glucans that retrain immune cells to identify and eliminate abnormal cells before they become visible growths. The probiotics restore the gut health that makes that immune function possible. One fixes the system. The other keeps it running. Surgery does neither.

We're not asking you to skip necessary care. If your vet has concerns about malignancy or mobility, follow that guidance. What surgery doesn't answer is why your dog keeps producing lumps. CanisPSP™ targets that question. Many owners use both — surgery for urgent lumps, this formula to address the root cause preventing new ones.

Both. Most owners report visible softening and reduction of existing lumps between weeks four and six, with the smallest lumps often resolving first. Stopping new lump formation is the long-term goal. Reduction of existing lumps is typically what owners notice first.

Most owners notice increased energy and vitality within one to two weeks — the immune system responding before visible changes appear. Visible lump changes typically begin around weeks four to six. That's why we offer 90 days, not 30. The mechanism takes time. The guarantee gives it that time.

Age and lump count don't determine whether this works — consistency does. Chislaine's 10-year-old corgi with multiple recurring lipomas saw 25% reduction in 1.5 months. A 9-year-old Golden with mobility-affecting lumps had smaller ones undetectable by the next vet appointment. Daily use is what matters most.

The University of Pennsylvania research is peer-reviewed and documented. But conventional vets are trained around diagnosis and procedure — nutritional interventions rarely make it into a ten-minute appointment even when the research exists. Your vet not mentioning it is not evidence it doesn't work. We encourage you to share the UPenn research with them directly.

Turkey Tail has a strong safety profile in dogs with no significant adverse effects noted in the UPenn studies. Some dogs experience mild stool changes in the first few days as the gut microbiome adjusts — this resolves quickly. CanisPSP™ is USDA Organic and NASC Certified. If your dog is on existing medications, loop your vet in before starting.

No catch. Use it for 90 days. If you don't see results, email us for a full refund. Keep the product. No return, no documentation, no questions. We offer 90 days because that's what the research says the mechanism actually needs — and we'd rather carry the risk than have you quit at week six before results arrive.

Two reasons. Most supplements use mycelium on grain — not the whole fruiting body where PSP concentrations are meaningful. And Turkey Tail alone cannot fix immune surveillance if the gut isn't also being restored. Without probiotics, you're addressing one side of a two-sided failure. CanisPSP™ is the only formula that combines both at clinical concentrations.
