While antlers are a popular chew option for many dogs, there are some reasons why dogs shouldn't chew on them, especially unsupervised or for extended periods.

One concern is the risk of dental damage. Antlers are extremely hard and dense, making them challenging for dogs to chew without risking dental fractures or breakage. Chewing on hard surfaces can also exacerbate existing dental issues, such as cracked or broken teeth.

Additionally, while antlers are less likely to splinter than cooked bones, there is still a risk of small pieces breaking off and causing choking or intestinal blockages, especially in dogs who are aggressive chewers or prone to swallowing large chunks of food.

Some dogs may also become overly possessive of their antlers, leading to resource guarding behavior or conflicts with other pets in the household. To prevent these issues, it's essential to supervise your dog while they're enjoying their antler and to remove it if any signs of aggression or possessiveness arise.

Ultimately, while antlers can be a safe and enjoyable chew option for some dogs, they may not be suitable for every dog, especially those with dental issues or aggressive chewing habits. It's essential to monitor your dog's chew habits and choose appropriate chew toys to keep them safe and healthy.
