What to Look for in a Dog Chew Besides How Long It Lasts

Durability gets all the attention when it comes to dog chews, and it makes sense. Nobody wants to spend money on something their dog demolishes in four minutes. But longevity is really just one piece of the picture, and it’s probably not even the most important one. A chew can last all afternoon and still be doing your dog more harm than good if the ingredients, texture, or size aren’t right for them. 

Dog owners across the US are becoming more thoughtful about what they give their pets, and that shift reflects something real: the chew your dog spends time with every day deserves the same level of scrutiny as anything else in their diet.

Here is what actually matters when you’re evaluating a dog chew.

1. The Ingredient List

Most dog chew packaging leads with flavor, texture, or some kind of benefit claim. The ingredient list, usually in small print on the back, is where the real story is. Single-ingredient chews made from natural animal parts, things like bully sticks, tendons, ears, or dried meat, are generally easier on a dog’s digestive system than chews loaded with artificial preservatives, added colors, or fillers that serve no nutritional purpose.

The shorter and more recognizable the ingredient list, the better. If you can’t identify what something is or why it’s in there, that’s worth a second look before you buy. Dogs chew for extended periods, which means whatever is in the chew is being slowly consumed over time, and that makes ingredient quality a more significant factor than it might seem at first glance.

2. Chew Hardness

Chews that are too hard for a dog’s teeth can cause fractures, particularly in older dogs or dogs with existing dental issues. A common rule of thumb used by veterinary dentists is the thumbnail test: if you press your thumbnail firmly into the chew and it leaves no mark, the chew is likely too hard for safe chewing.

When shopping for long lasting dog chews, most people assume harder means it will last longer, but that’s not always true and it’s not always safe. Natural chews made from animal-based ingredients can hold up well over extended chewing sessions while still having enough give to protect the teeth. Some brands such as Bully Bunches often offer single-ingredient chews that strike that balance, durable enough to satisfy aggressive chewers without crossing into the hardness range that puts teeth at risk. That distinction is worth looking for specifically rather than defaulting to the hardest option on the shelf.

3. Size Relative to Your Dog

A chew that’s too small for a dog’s mouth becomes a choking hazard once it gets worn down to a certain point. This is especially relevant for larger dogs who can reduce a chew to a small piece faster than expected. The chew should always be large enough that the dog can’t fit the whole thing in their mouth at once, and you should be paying attention as it gets smaller rather than leaving the dog unsupervised with a chew that’s reached a risky size.

Conversely, a chew that’s too large and rigid for a small dog can cause jaw fatigue or frustration, which defeats the purpose entirely. Matching the chew to the dog’s size, chewing style, and strength is a more individualized decision than most product recommendations acknowledge.

4. Digestibility

Digestibility is one of the key factors to consider when evaluating any chew, and natural protein-based chews generally fare better than synthetic alternatives in this regard. What a dog can’t digest well doesn’t just cause stomach upset. It can lead to blockages, which are serious and sometimes life-threatening. Some chews, particularly those made from synthetic materials or certain rawhide products, don’t break down well in a dog’s digestive system and can cause real problems if pieces are swallowed.

If a chew splinters into sharp pieces or produces large chunks that could be swallowed whole, it’s worth reconsidering regardless of how long it lasts.

5. The Caloric Content

Dog chews are food. They have calories, fat, and protein, and those numbers need to be accounted for as part of the dog’s overall daily intake, not treated as a separate category. A high-value chew given daily to a smaller dog can represent a meaningful portion of their caloric needs, and ignoring that over time can contribute to weight gain.

A 2025 study has associated obesity in dogs with a range of health conditions, including joint problems, diabetes, and reduced life expectancy. Checking the caloric content of a chew and factoring it into daily feeding is a simple step that makes a real difference over time, especially for dogs who chew regularly.

Final Thoughts

A good dog chew does more than keep your dog busy. It supports dental health, satisfies a natural instinct, and gives your dog something to genuinely enjoy. Getting to that outcome means thinking past durability and looking at what the chew is made of, how hard it is, whether it’s the right size, how well it digests, and how it fits into the overall diet. 

Those five things together give you a much clearer picture of whether a chew is actually good for your dog, not just good at lasting.
