"I love this collar. I went threw about 3 other brands and nothing fit my English bulldog correctly. He has neck rolls that most bullies have so it was never a right fit. I thought this one was too big when I first saw it but when it's on it doesn't fall off and is comfy enough to sleep in. It is soft and cushy for my bulldog's neck. I would like to be able to adjust it tighter but I understand because bullies can't have anything tight on the neck. I did see a couple of reviews that said it falls off when they are walking their bulldog however like in the instructions this collar is NOT meant to be used with a leash! Bulldogs cannot wear collars around the neck that pull. Only a harness or vests. I needed mine for his air tag collar so I bought an air tag holder that is extra wide to fit.Thx 😊 for caring and understanding the Bulldog breed! Safety first!Will be a customer for life."
