Safety First:
These heavy-duty chews require close supervision due to containing bone. Swallowing bone, regardless of size, is a behavior that should be prevented.

We have sold hundreds of these chews with no negative issues. However, we would prefer that you consider the potential hazards of these chews before buying.

Hog feet include marble-size knucklebones once the foot is broken down. Please discard these bones once they are visible. For smaller dogs, these bones could be considered a choking hazard. For larger dogs, we would expect the dog to either easily pass the bone or, depending on their diet, their stomach could break the bone down.

While we think they are safe when fed properly, there are extra precautions we recommend when giving these chews:

1. Ensure that these are being given to larger dogs
2. Ensure your dog's chewing habits/style are appropriate for dehydrated bone
3. Always supervise your dog when consuming any chew and remove pieces of the chew that break off during chewing
   

We always want to proceed with extra caution as the last thing we want to do is put you and your dog(s) in a dangerous situation.

If this product splinters or develops sharp edges, throw it away immediately for your pet’s safety. To prevent injury and choking hazards, please watch your pet while they enjoy this chew, and be sure to give the appropriate size/amount.

Chewing is one of the best mental and physical activities a dog can participate in!

Teeth
Want to save your dog from dental disease, horrible breath, and teeth cleaning bills? Then give your dog a chew for around 10 minutes every day!

Similar to humans, canine dental issues can impact the overall health of your pet! Not only is gnawing and chewing a great mental and physical exercise, but it cleans teeth and strengthens gums! Daily chewing is just like brushing teeth for humans!

Chewing
Limit chewing to 15-20 minutes per session. Most dogs feel fully satisfied (endorphins get released in the brain) after short sessions of back-of-the-jaw gnawing. After chewing, store the hide out of sight and give again when you need the pup to have some down time!

Safety
All chewing should be supervised, especially when your dog is trying something for the first time. When giving chews that have dehydrated bone, you want to make sure the dog has the jaw strength and patience to chew/crush the bones before consuming. If a sharp edge or inappropriate chewing behavior is ever discovered, we recommend removing the chew for safety reasons.

Storage
Keep in a cool/dry place. Our dehydrated products are free of preservatives and pesticides, and although it is very uncommon, bugs and mold (from added moisture) are your two culprits for causing trouble.

For chews and hides, especially after a chewing session, avoid sealing them in plastic or containers that can trap moisture. Allow the chew to air out and store in a cool/dry place.

For longer storage, the freezer can be a great way to keep our products fresh, and away from bugs and pest that might show interest.
