Dog Accessories Buying Guide: What to Look For

For the full breakdown, see our best Dog Accessories guide.

Shopping for dog gear gets expensive fast, and the wrong pick wastes money or puts your dog at risk. A crate that’s too small, a harness that rubs, or a toy with parts that break off are all common failures. The buying decisions that matter most — fit, safety, durability, and whether the item actually does its job — don’t change much between products. Get those four right and you can shop with confidence across any brand or price point.

If you’re ready to compare specific products side by side, our tested roundup of top-rated options is worth a look once you know what to check for.

How to Size a Dog Crate Correctly

A crate is the right size when your dog can stand up without crouching, turn around easily, and lie down with legs fully extended. Most sizing mistakes come from buying by weight alone rather than measuring the actual dog.

Take two measurements before you shop: nose-to-tail length and standing height from floor to top of head. Then add 2 to 4 inches to each measurement to find your crate size, since dogs need clearance above the head and room to stretch out. A common rule of thumb says a sitting dog should have at least 2 inches of headroom.

Weight-based charts help narrow options but vary by brand and breed shape. A typical reference chart maps dogs up to 25 pounds to a 22-inch crate, 26–40 pounds to a 30-inch, 41–70 pounds to a 36-inch, 71–90 pounds to a 42-inch, and 91–110 pounds to a 48-inch. Dogs over 110 pounds generally need a 54-inch crate. Check the manufacturer’s exact dimensions against your dog’s measurements before buying, since crate styles and brands differ noticeably.

What Makes a Harness or Collar Fit Well

A harness should sit behind the shoulder blades and stay put during movement — if it shifts forward or rubs the neck, it’s the wrong fit. The “two-finger” rule applies across collars and harnesses: snug enough that it won’t slip off, loose enough that two fingers slide easily underneath.

Check the manufacturer’s size chart for both neck circumference and strap width, not just the size label. Widths and neck ranges vary widely between brands. Look for reinforced stitching and sturdy metal hardware at load-bearing points — weak seams and brittle plastic buckles are the most common failure points on lower-quality gear.

Choosing Safe Toys and Chew Items

Toy safety comes down to size and detachable parts. Buy toys sized for your dog — something too small becomes a choking hazard, and something too large may be unusable. Before letting your dog play with any new toy, remove ribbons, strings, plastic eyes, and similar parts that can be chewed off and swallowed.

Aggressive chewers need toys that are genuinely tough. If a toy isn’t labeled for heavy chewing, treat it as supervised-play-only. The Humane Society advises choosing toys appropriate for your dog’s chewing style and discarding any toy that starts breaking into pieces.

Regardless of what you buy, inspect accessories regularly. Retire any item with broken seams, cracked plastic, loose threads, or damaged hardware the moment you spot the problem.

Safety Checks Before You Buy

A few minutes of verification before purchase prevents most accessory-related problems. Search for recalls on the exact product or model — the U.S. Consumer Product Safety Commission database covers pet products, and brand-specific recall pages fill in the gaps. Material claims deserve scrutiny too: check for toxic or questionable materials, unsafe metal coatings, and construction flaws like brittle plastics.

For crates and carriers, latching matters most. Look for secure, dual latching mechanisms on carriers and solid door hardware on crates — a determined dog can defeat a single weak latch. If a product has a recall history for a specific defect, skip that model entirely.
