Sienna has a collection, too. Being a Sheltie mix, she has that Sheltie mane so flat buckle collars look really weird on her - they push all her fur up around her face so she kinda looks like a lion with an afro, lol. So for her tags, she wears a rolled leather collar that's buckled loose so it rests at the base of her neck, near her shoulders. Wasn't the cheapest collar, but it flatters her and it will last forever.
The leather collar is *really* loose, though, and she'll slip out of it, so the leash attaches to a martingale. The martingale tends to get her white chest dirty, and the fit closely resemble that of the flat buckle collar. So I got her a metal 'choke chain' type collar which I use sometimes instead of the martingale. Actually, the leather collar also turns her white fur dingy, so she doesn't wear it around the house, and sometimes I just walk her on the choker. After a bath, sometimes the tags even go on the choker!
Until I walk down to the coffee shop and have to tie her out front while I order, then I remember why I have a martingale.
She also has a couple of harnesses, which I bought for several reasons. First, I liked the idea of a harness vs. a collar. Second, I thought they might look better on her than the flat buckle collars (see lion with afro, above
) Nope, she looks just as weird in a harness. Third, she doesn't walk on the flexi lead, because she's so sensitive to the tension she won't pull against it, so I thought a harness might help with that. Nope.
Although, like BostonBanker's dog, she does wear it on the boat so I can fish her out if she falls in!
So that's one rolled leather collar, one martingale, one choke chain, two harnesses....sheesh, I didn't mean to write a novel about collars!
ETA: I'm kinda jealous of you guys that can buy cute buckle collar for your dogs!
