I've used many different weight collars over the years. This Canine Athletes weight collar is by far and away the best constructed and most functional I've ever used. I'm surprised it's not more expensive haha
I own two presa canarios and this is a great buy! Excellent addition to the cardio
I got the 3lb version for my large Malinois and the 5lb for my American Bulldog to enhance their walks. The 3" wide is a little large for my APBT, so I don't use it with her. I'll wait for a 2-2.5"W model for her. She is significantly smaller than the other two - I just wish there was more than one width option available. Otherwise, awesome product and I look forward to results with the bigger hounds.
