Ensure the Right Fit

Use the “two finger” rule: Once the dog's collar is fastened, you should be able to easily slide two fingers under the collar. When you slide the width of your two fingers between the collar and neck, the collar should feel snug, but not tight. 


My dogs are not well trained, although their collars are AWESOME.  I keep all tags and such on their beaded collars, but have to use a pinch collar or harness to prevent them from pulling my shoulder out.  Trainer I am not.

That being said, one of my collars is on its second generation dog.  They last a long time and don't get stinky or dirty.
