Review on 🐾 Ultimate Durability: Cdycam Adjustable Double Thick Heavy Duty Tough Nylon Military Dog Collar with Metal D Ring & Buckle by Natasha Gibson

We were looking for large, durable collars. Which were a little hard to find. We have (2) Bullmastiffs. Our wife weighs 145 pounds and our husband weighs 125 pounds. We use an invisible WiFi fence on our 17 acres to ensure they stay on site. The wireless fence has boxes that match the collars. As they approach the perimeter, the crates will beep. If they try to break into the perimeter, the boxes have 1 inch spikes that will deliver a shock. The problem we always face is finding collars big enough so the needles don't dig into their throats. We actually removed the collars while they were inside because we didn't want them to be uncomfortable. When the collars arrived my husband said they reminded him of the military collars that dogs wear. He didn't think he could change the collars to add drawers because of the need to make holes for pens. He was able to modify collars even with solid construction. We no longer have to remove collars when our dogs are around the house and everyone is happy without worrying about the needles digging into our dog's throat. We would highly recommend these collars and would buy them again if the need arose. Another nice feature is the large, durable metal loop. People who have collars like ours know we have a responsibility to keep them under control when a delivery is due or someone just walks in, we have the option to grab a metal loop to reattach it or bring it inside. Thor and Isabella, thank you! In the photo they are without new collars. I just wanted to show their size for comparison. Big dogs with big heads and necks! I only gave 3 stars for stretch because these collars do not stretch as that defeats the purpose! 😉
