Details
Our 100% natural, grain-free, plant-based treats have a deliberately firm texture and angular profile to prolong the eating time and promote teeth cleaning. But you can afford to be generous; these healthy morsels only contain 1 calorie per treat, perfect for training.
What do they taste like?
We have three uniquely named flavours, each with its own identities.
Slipper & Biscuit
Save your slippers and consume fewer biscuits — let our treat fill the void. Slipper & Biscuit’s green and yellow colours are flavoured with pooch favourite peanut butter. The contrasting green is the natural result of adding broccoli and breath freshening apple.
W’ZIS flavour scale: WW

FAQs
Where can I buy W’ZIS?
How many calories are in your treats?
Our small ‘W’ treats are just 1 calorie each meaning you can reward generously.
Are your treats suitable for dogs with dietary issues?
You will always need to consult your vet if you have any doubts, but generally, our treats are popular with dog owners whose pooches have allergies, kidney issues or other sensitivities to food.
How do you pronounce W’ZIS?
“What’s this?” It is what most hoomans say when they treat their dog. It is the treat name that dogs have already heard of.
Can I give W’ZIS treats to my puppy?
We recommend you wait for your pup to reach 4 months (16 weeks).
How long is the shelf life?
We recommend consuming W’ZIS products within 6 weeks of opening as the appealing aroma (to dogs) will start to fade. Due to the very low moisture content, a sealed W’ZIS product will last up to 36 months.

Need to pop out and leave your dog unattended?
Do the W’ZIS scatter and go.
