Some dogs can eat anything and bounce off like nothing happened. Others? Not so lucky. If you’ve got a Dalmatian or another breed prone to purine intolerance, you’ll know what a minefield food and treats can be. Here’s where W’ZIS comes in.
What’s the Deal with Purines?
- Purines are natural compounds found in food, especially in meat, offal, oily fish, and yeast.
- When dogs metabolise purines, they produce uric acid.
- Most dogs convert uric acid into allantoin, which is easy to excrete.
- But Dalmatians (and a few other breeds) can’t do that efficiently. Too much uric acid → crystals and stones in the urinary tract. Painful, dangerous, and totally avoidable with the right diet.
Where W’ZIS Fits In
Our treats sit at around 5% protein — that’s low compared to most dog treats, which often push past 20–30% protein and come loaded with meat by-products. Here’s why W’ZIS matters if your dog needs to keep purines in check:
- Plant-Based by Design. We avoid meat, offal, and fish altogether. Lower purine load right from the start.
- 5% Protein. Much lighter on purine contribution than high-protein biscuits or meat chews.
- Clean Ingredients. Sweet potato, pea flour, fruit, and veg. No hidden nasties.
- Hypoallergenic. Grain-free, dairy-free, sugar-free. Less risk of inflammation on top of purine issues.
- 1 Calorie Each (Rewards). You can use them freely in training without blowing their daily allowances.
Which Dogs Should You Care About?
- Dalmatians. Genetically prone to purine intolerance.
- Bulldogs, Black Russian Terriers, and some Retrievers. Can also be at higher risk.
- Any dog with a history of urate stones. Needs a low-purine diet as part of management.
Smart Treating for Purine-Sensitive Dogs
- Stick to low-protein, plant-based treats. Like W’ZIS Reward Treats and Dubya Chews.
- Use variety, not volume. Reward often, but keep treats small (ours are 1 calorie for a reason).
- Balance with their main diet. Treats should never push protein levels higher than what your vet recommends.
- Watch the extras. Skip liver snacks, fish skins, or meaty chews. They’re purine bombs.
