A long-lasting chew made from milk that’s naturally built to last for yonks.
Chewing is a natural, feel-good behaviour for dogs - it keeps their minds busy, their teeth clean, and their stress levels low.
It’s how they explore the world, unwind after a busy day of being brilliant, and channel all that joyful energy into something positive (and not your favourite slippers).
Giving your dog the right chew means happier tummies, healthier teeth, and a calmer, more content pup - exactly the kind of everyday goodness we’re all about at Butternut Box.
Our Yonks Bars are suitable for all dogs over 5kg and puppies over 4 months. We do recommend sizing up, so they’re the right fit in both size and durability. For example, if your dog is around 7kg but a really strong chewer, a medium bar could be the better choice.
Please make sure you order a bar that is suitable for your dog. If you are unsure, it’s always better to size up rather than size down and always check with your vet.
Are they suitable for puppies?
We’d recommend these chews for puppies 4 months and older due to their puppy teeth. For context, puppies have 28 “baby” teeth, which are replaced with adult teeth from the age of 3-7 months. New adult teeth have thinner and softer enamel layers (the white bit of our teeth) so daily use of hard chews could lead to wearing this enamel down. So we wouldn’t recommend pooches under one to have a chew a day.

Keep an eye out
Make sure you’re keeping an eye on your dog as they’re enjoying their Yonks Bar, to check they’re chewing it safely, and not gulping it down like it’s about to disappear.
Important: Feed as a treat between meals, as part of a balanced diet. Chews can be a choking hazard, particularly when there's only a small bit left.
Always make sure that clean water is available. Our Yonks bars are hard chews, which makes them long-lasting, and possibly unsuitable for senior dogs or dogs with dental concerns.
There may be a bit left that’s too small eat - pop it in the microwave for 90 seconds at 800 watts, then leave to cool for 2 mins. Remember: All microwaves are different. Always watch your Yonks Bar whilst heating, and remove as soon as it’s puffed up.
