Every once in a while, one hears of a collar accident. This past week I encountered two -- Laev caught her martingale on a borrowed drop-pin crate, and a client's dog caught her flat bucklet collar on her backyard fence.
I was there when Laev's crate came apart and she leapt out, dragging three interlinked panels behind her by her collar. She was unhurt and unfazed, thinking it was great fun, but it could have been serious if she had tangled and the collar had tightened. The other dog, a sweet and intelligent Labrador mix, died in her accident.
But it's not practical to leave a dog without visible ID; I received another phone call this morning regarding a lost dog. There has to be a happy compromise.
I have seen safety collars before, but the best design has to be the one offered by Tazlab. Unlike some other models, these are safe and at the same time useful as a collar. They actually are sturdy -- I tested one by placing it on Laev and then releasing a cat. If the collar held through that, it isn't going to break easily.
I get no reimbursement for recommending these, but Shakespeare is wearing one now. I keep visible ID on my dogs in case someone leaves a gate open, or I am in a car accident and their crates break open, or any number of odd things. I feel this is the best of both worlds, at least.
