"I tried these collars on my two small senior dogs. Unfortunately, after a month, their health declined dramatically. My male became lethargic and lost weight, while my female became unresponsive.

"I was thrilled that my Rat Terrier and pit mix stopped scratching just minutes after I put the collar on. It's been a great purchase for us!"

I recommend monitoring your dog closely, especially at first."

"I had high hopes for this flea collar for my Shih Tzu, who had a few fleas. I bathed him, then applied the collar, but after two days, he started scratching excessively. To my dismay, I found a lot of fleas on him. This collar didn’t work for us, and I regret not going for a more expensive brand."

"This was my first experience with a flea collar, and I wanted it to work. The smell was better than I expected, but after three days, I noticed my dog scratching her neck, and it developed into a red spot. I had to remove it because it seemed to cause her pain. I learned my lesson!"

"My dog is allergic to grass, so keeping her irritant-free is really important. With these collars, she quickly had no fleas and no scratching.

Overall, the functionality and ease of use are perfect for my senior dog."

"I absolutely love the scent of this collar! It has a soft lavender/vanilla aroma. The size was perfect for my 74 lbs dog and 6 lbs papillon. I’ve dealt with sand fleas from my backyard, and this collar worked wonders; within 48 hours, the fleas were gone. No more itching at bedtime! I'm very pleased with its killing ability."

"I was really hopeful for these collars due to a terrible fleas situation this year. They seem to work for killing fleas but don't stay on. Out of four collars, only one managed to stay on my dog. I noticed her fur is growing back from irritation, but I still find live fleas occasionally. They might be effective in killing fleas when they bite, but a better buckle design is needed."

"We have various sizes of dogs, and buying individual collars was too costly. After reading reviews, we tried these and were pleased—one week later, all our dogs, from Chihuahuas to German Shepherd, are flea-free! The collars are easy to fit, stylish, and have a nice scent. No reactions or issues, all at a fraction of the cost!"
