The fastening on a collar affects how it feels to use and how it behaves in different situations. Here are the common types.
Buckle collars
A traditional buckle works like a belt. It's adjustable and holds securely once fastened.
Good for: Everyday wear and walks where you want a firm hold.
Consider: It takes a moment to fasten and unfasten.
Clip or quick-release collars
A plastic or metal clip snaps together, making the collar quick to put on.
Good for: Owners who want speed and convenience.
Consider: Check the clip quality regularly. Cheap clips can wear.
Breakaway collars
Breakaway collars are designed to release under a certain amount of force. They're more common for cats, and some owners use them for dogs that are at risk of getting caught.
Good for: Situations where snagging is a concern.
Consider: They may release when you don't want them to, such as when a dog pulls on the lead, so they're generally not used for lead walking. Ask a trainer or vet for advice.
Which is right?
It depends on your dog and how you'll use the collar. Ask yourself:
- Does my dog pull on the lead?
- Does my dog wear the collar all day, or just for walks?
- Is there a snagging risk, such as in bushland or with other dogs?
Matching the fastening to the situation
Everyday wear. A buckle or clip that stays put and is easy to adjust works for most dogs.
Frequent on-and-off. If you take the collar off often, for example for grooming or swimming, a quick-release fastening saves time.
Dogs that pull. Choose a fastening you trust to stay closed under load, and think about a harness for walks. Ask a trainer.
Dogs at risk of snagging. If your dog plays in bushes or rough terrain, ask your vet or trainer whether a different collar type suits you.
Checking any fastening
- Fasten it and give it a firm tug to confirm it holds.
- Look for cracks in plastic clips.
- Check metal buckles for bending or wear.
- Make sure the tongue of a buckle sits in the hole squarely.
- Re-check regularly, especially if your dog is strong or active.
Frequently asked questions
Which fastening is most secure?
It depends on the quality of the hardware and how it's used. Check any collar you buy for solid construction.
Are breakaway collars suitable for lead walking?
They're designed to release under force, so many owners use them for wear at home rather than on the lead. Ask a trainer.
Do clips wear out?
Any moving part can wear. Check them regularly and replace the collar if a clip loosens.
Can a collar open by itself?
A properly fastened collar shouldn't. If it does, replace it.
What does the ring do?
The D-ring is where you attach a lead and tags. Check it's securely attached.
