The Right Chew for Every Dog: A Breed & Size Safety Guide

“A chew that's perfect for your Staffy could be a genuine hazard for your neighbour's Frenchie. Size isn't optional — it's the whole safety plan.”

As a house that lives with Staffiords and French Bulldogs, we know firsthand that “small dog” and “gentle chewer” aren't always the same thing — and that a big, powerful dog doesn't automatically need the hardest chew on the shelf.

Sizing treats correctly is about matching the chew to your individual dog's jaw strength, chewing style and life stage, not just their breed label. Get it wrong in either direction and you're either wasting a good chew or creating a genuine hazard.

The quick answer

The Golden Rule of Chew Safety

A safe chew should be large enough that your dog can't fit the whole thing in their mouth at once — this prevents gulping and reduces choking risk. It should also be appropriately matched to your dog's bite force: too hard, and you risk a fractured tooth; too soft for a determined chewer, and large pieces can break off and be swallowed whole. Always supervise chewing sessions, provide fresh water, and remove any chew once it's worn down small enough to pose a hazard.

Small Dogs (Under 10kg)

Think Chihuahuas, Toy Poodles, small / young Frenchies, and other toy or small breeds. Small dogs have proportionally strong jaws for their size, so “small” doesn't mean “no supervision needed” — but it does mean sizing everything down.

• Whinny & Co Goat's Ears — naturally smaller than venison or cow ears, a popular pick for small-to-medium dogs and a good option for pets with allergies to other proteins.
• Lung Bites (Beef, Lamb or Venison) — light, soft-textured and easy to break into tiny training pieces, ideal for small mouths and sensitive teeth.
• Beef Jerky Sticks — a light, easy-to-manage everyday treat.

Medium Dogs (10-25kg)

Kelpies, Cocker Spaniels, French Bulldogs, Staffordshire Bull Terrieres, Border Collies and similar. Medium dogs generally have the jaw strength to handle standard-format chews and enjoy a bit more of a challenge than a toy breed.

• Bull Pizzle Sticks — a single-ingredient, long-lasting chew that suits the moderate-to-determined chewers common in this weight range.
• Lamb & Cheese Bites, Venison & Cheese Bites — high-value training treats that work well for active, food-motivated medium breeds.
• Busy Bone — a satisfying, long-session chew that suits large dogs who need real jaw work to stay settled and occupied.

Large & Giant Breeds (25kg+)

Labradors, Rottweilers, larger AmStaffs, and other powerful chewers need chews that can stand up to serious jaw pressure without breaking into swallowable chunks too quickly. Large and giant breeds need chews sized up, not down — a chew built for a small dog will be gone in seconds and offers little safety margin against gulping.

• Cow Hooves — a genuinely long-lasting option for strong, confident chewers, always given under supervision and swapped out once worn down.
• Busy Bones — a satisfying, long-session chew that suits large dogs who need real jaw work to stay settled and occupied.
• Bulk Bull Pizzle Sticks — the bulk format is ideal for larger dogs who work through chews quickly, or multi-dog large-breed households.

Puppies and Teething Dogs

Regardless of what breed they'll grow into, puppies need softer options while their adult teeth come through. Lung Bites are a good match here — light, soft-textured, and easy to break into pieces small enough for a puppy's developing bite. Save harder whole chews like hooves and pizzle sticks until adult teeth are fully in and your puppy has built up some chewing experience.

Senior Dogs

Older dogs often lose some bite force and can develop dental sensitivity, so softer, more digestible options are usually the better everyday choice. Lung Bites and Lamb & Cheese Bites both offer a satisfying, flavourful treat without demanding the same jaw effort as a whole hoof or pizzle stick.

FAQ

Frequently Asked Questions

How do I know what size chew is safe for my dog?

As a rule of thumb, a chew should be large enough that it can't fit entirely inside your dog's mouth, but not so large or hard that your dog can't get a grip or work their jaw comfortably. Match sizing to weight: small dogs under 10kg, medium dogs 10-25kg, and large or giant breeds over 25kg each need different formats.

Are hard chews like cow hooves and bull pizzles safe for all dogs?

Harder, longer-lasting chews suit confident, supervised adult chewers rather than puppies, seniors, or dogs with dental sensitivities. Always supervise chewing and remove any chew once it's worn down small enough to be a choking risk.

What treats are best for puppies who are teething?

Softer, smaller options like Lung Bites are gentler on developing teeth and gums than harder whole chews, which are best introduced once adult teeth are fully in.

My dog is a Staffy/AmStaff type with a strong jaw — what should I look for?

Strong, determined chewers do well with longer-lasting whole chews like Bull Pizzle Sticks, Cow Hooves and Busy Bones, always given under supervision and sized up rather than down.
