How Should a Dog Coat Fit? 9 Fit Checks (and the Most Common Mistakes)
Quick answer: what a good fit looks like
A dog coat should fit snugly but not tight, covering the back and chest without restricting movement. It should stay in place, avoid rubbing, and allow your dog to walk, run, and sit comfortably.
Fit check in 30 seconds
- Can you slide two fingers under the coat at the neck and chest?
- Does the coat cover from base of neck to base of tail?
- Are the shoulders and front legs free to move?
- Is there no bunching behind the front legs?
- Does the coat sit straight, not twist to one side?
- Is the belly covered (if intended), but not tight?
- No rubbing or redness under the arms or chest?
- Can your dog toilet comfortably with the coat on?
- Does your dog seem happy to move in it?
Common fit problems (and fixes)
Rubbing behind front legs
Often caused by straps that are too tight or a coat that’s too short. Loosen straps or size up.
Twisting/slipping to one side
Check the straps are even and snug. If it still twists, the coat may be too big or the wrong shape for your dog.
Riding up the back
Usually means the coat is too short or not fastened securely.
Restricting shoulders
Shoulders should move freely—try a different style if your dog seems stiff.
Waterproof vs drying coat fit: what’s different?
Waterproof coats often have a closer, more tailored fit. Drying coats (like Ruff & Tumble) are looser for absorbency but should still cover the key areas.
When to size up vs adjust straps
If the coat is just a bit tight, try loosening straps. If it’s still restrictive or short, size up.
