Deer antlers, which are naturally shed products from the cervid family, have become a popular choice for long-lasting dog chews. These chews offer a mineral-rich option for dogs with a strong urge to gnaw and can provide hours of mental stimulation. However, the safety of these extremely dense chews is a highly debated subject among veterinary professionals and dog owners alike. A proper safety assessment requires a detailed understanding of the material’s properties and the potential for dental injury.
Understanding the Risk of Tooth Fractures
The primary concern regarding deer antlers is their extreme hardness, which does not yield when a dog applies force. Antlers, particularly those from Whitetail deer, are among the densest types, possessing a solid, thick outer cortex. This lack of give means the dog’s tooth is likely to fracture before the antler is crushed or broken down.
The most common injury resulting from chewing hard objects is a slab fracture. This trauma occurs when a dog bites down on the antler, causing a segment, or “slab,” of the tooth’s crown to break off. The tooth most frequently affected is the upper fourth premolar, also known as the carnassial tooth, which is the largest tooth used for chewing and shearing.
When a slab fracture extends deep enough, it exposes the sensitive pulp cavity, which contains the nerve and blood vessels. This exposure is painful and creates a direct pathway for bacteria, leading to infection or an abscess. Fractures that expose the pulp require professional veterinary intervention, typically involving a root canal procedure or surgical extraction. Owners often overlook these injuries because dogs instinctively hide dental pain, but an untreated fracture can cause chronic discomfort.
Choosing the Safest Antler Type and Size
Mitigating the risk of dental injury starts with selecting the appropriate antler type for a dog’s chewing style. Antler chews are available in two forms: whole and split. Whole antlers feature the hard, dense exterior and are the most durable choice, best suited for power chewers who gnaw rather than bite aggressively.
Split antlers are cut lengthwise to expose the softer, inner marrow, which is more enticing to the dog. This exposed interior reduces the initial pressure the dog must apply to access the desirable part of the chew. Split antlers are a safer option for moderate chewers, puppies with adult teeth, or older dogs, as they are less likely to cause a fracture than the hard outer shell of a whole antler.
Choosing an appropriate antler size is important to prevent both choking and aggressive biting. The antler’s diameter should be substantial enough that the dog cannot physically fit the entire chew inside its mouth. A general guideline is to select a chew that is longer than the dog’s muzzle to ensure it cannot be swallowed whole. Selecting an antler that is too small increases the likelihood that a dog will try to forcefully crunch it, raising the risk of dental breakage.
Protocols for Safe Chewing Supervision
The responsible use of deer antler chews requires constant supervision. Owners should monitor their dog’s behavior to ensure they are gently grinding, scraping, or licking the chew rather than aggressively biting the hard material. If a dog attempts to clamp down forcefully with its back molars—the action that causes slab fractures—the chew should be immediately removed and replaced with a softer alternative.
To encourage a dog’s interest and promote gentler chewing, the antler can be prepared beforehand. Soaking the antler in water overnight can slightly soften the exterior layer, making it less brittle and more pliable. This simple step helps reduce the initial impact pressure on the dog’s teeth.
Owners must maintain a strict protocol for when to discard the chew. An antler should be retired as soon as it becomes small enough to be swallowed whole, representing a choking or obstruction hazard. Regular inspection for sharp edges or splinters is necessary; any chew with these characteristics should be smoothed with sandpaper or immediately disposed of.
