I’d had a few groos (and other breeds) ‘slip’ their slip collars. Treacle for one, thankfully I grabbed her house collar before she went anywhere!
I’m not trying to be completely negative about slip collars, I definitely think they’re great for some dogs.
But I don’t think any collar is fool proof and I think it depends on the dog too - how they try to escape: forward or backward and if they struggle - whether or not a slip collar vs buckle vs gentle leader is a safer option.
If you’re really concerned, I would suggest getting a harness as they’re quite difficult for a dog to get out of (dogs don’t just slip properly put on harnesses, it takes a bit of work and struggling). That’s what my Coal wears as I know if he got loose we wouldn’t see him for quite some time!
Has Diesel increased in energy since I had him since I can’t imagine him running away very far?
Best,
