She is an Xolo 35 lbs 6 mo.
It's a little big, but surely she will grow into it. It makes alot of noise, so she doesn't like to wear it when in the back yard, since she can not sneek up on the rabbit and squirrels. she is smart enough to put her head down and slid out of it. LOL then i have to search the grass for it.
She loves to take walks with this colar and she walks nicely with it, without pulling.
