I'm sorry if this is in the wrong forum, it was the most suitable area I could find.

I just purchased 2 dominant dog collars from Leerburg, and I measured 3 times before ordering just to make sure I had my measurements correct. I measured Oxz at 19.5" (so I rounded down to 19") and I measured McCaskey at 16.25" (and again rounded down to 16"). For both dogs I tightened the measuring tape as much as I dared before I thought it would tear (it's a paper tape) and Oxz's neck is shaved currently so I didn't have to worry about hair adding length. Anyway, the collars arrived today and they are both too big. :\

The 16" just slides down McCaskey's neck, but if I put it on Oxz it stays put right where it belongs, but it only yields about 1" of slack, if you could call it "slack"; I suppose it would be more accurate to say that it has 1" of "give". Is this a suitable amount of slack, or should I exchange both collars down a size or two? (For reference, the 19" collar yields 3" of slack on Oxz. And the 16" yields 3-4" of slack on McCaskey. I'm 100% sure I measured correctly, I even watched the video again to quadruple make sure.) But I suppose I didn't take into account that McCaskey has short hair (pit-mix) and doesn't have any ruff like a Malinois or GSD to help keep in place...

With the 16" on Oxz, I can get 1-2 fingers under the collar under her jaw, but I'm also wondering how much room there will be when her hair grows back in full. (Black Russian Terrier = Lots 'o Hair) Would it be better to get a 17"? I'm sorry, I'm not being very concise...side effect of being exhausted. Any help is greatly appreciated!

Gah! How clever are you?! Thank you very much...I would not have thought of that.

Excellent Aaron! Boy, do I feel stupid now for thinking she'd need to exchange them. Simple fix.
