Low-purine food for Dalmatians after stones

Dalmatians and urate stones are a well-known combination — it's a breed-specific metabolic quirk, not bad luck. The good news is that once stones are cleared, the right maintenance diet genuinely does reduce recurrence risk, and your vet has clearly done the hard work of getting you to this point. Before I point you toward something specific: what is he or she currently eating, and did your vet flag any particular purine threshold to stay under, or just give general low-purine guidance?

That's a solid handover from the prescription phase. Three months on the urinary diet post-clearance is about right, and 22kg is typical for a female Dalmatian. The key thing to understand with Dalmatians is that they can't metabolise purines the same way other dogs do — even healthy Dalmatians convert purines to uric acid rather than allantoin, which is why high-protein, organ-heavy, or fish-heavy foods are a recurring problem for the breed regardless of stone history. You want a food that's moderate in protein, uses lower-purine protein sources like chicken or egg rather than red meat or offal, and doesn't rely on fish meal. Can I ask — is she on wet food, dry, or a mix?

Good — dry is fine for this, and the right kibble makes long-term management straightforward. My recommendation for a maintenance Dalmatian with confirmed stone history is Hill's Science Plan Adult Large Breed with Chicken. I know 'large breed' sounds odd for a 22kg dog, but it's worth choosing here because the formulation is lower in phosphorus, moderate in protein, and uses chicken as the primary source rather than red meat or organ-rich blends. Hill's is consistent in its ingredient sourcing, widely available, and — importantly — it's not a food that sneaks in high-purine ingredients like liver or herring meal under vague labels. The protein level sits around 23–24%, which is appropriate for maintaining muscle without purine loading. You'd feed roughly 280–310g per day for her weight, split into two meals. I'd also encourage you to keep her well hydrated — wet food toppers or a water fountain can help, as dilute urine is one of the best passive protections against stone recurrence.

Yes, and it's a useful thing to know. Avoid foods where the first few ingredients include liver, kidney, heart, or any organ meat — these are very high in purines. Also be cautious with foods that list 'fish meal' or 'anchovy' high on the label, and avoid game meats like venison or rabbit as primary proteins, which can also be purine-heavy. Yeast extract is another one to watch — it's sometimes added as a flavour enhancer and is surprisingly high in purines. Chicken, egg, and to a lesser extent turkey are your safer protein sources. If you ever want to switch brands, just cross-check the first three protein sources against that list and you'll catch most of the problem foods quickly.

Great choice for the long term. One last practical note — transition her gradually over about a week, mixing the new food in with the remaining prescription food, even though it's a softer transition than starting from scratch. Her gut has been on a fairly specific diet for three months, so a slow swap just keeps things settled. And it's worth a quick check-in with your vet at her next routine appointment to confirm she's maintaining well on it — they may want to run a urine pH test periodically, which is straightforward and gives you peace of mind.
