Put me down as a fan of Lewis Dog Boots. I boot my dogs quite frequently when hunting in far southwest Kansas. Sand burrs and goat heads are tough, but running though the rock and outcroppings chasing quail in the southwest part of the state will take the pads off of any dog.
I've never lost a Lewis boot and my dogs don't have a problem wearing them.
I'd really like to use another brand as Lewis boots are time consuming to put on properly, but I've never been able to keep another brand of boots on a hard running dog. There's is a "trick" (and and art) to putting Lewis boots on.
The key is to put a 3/4"piece of athletic tape (sticky side out) around the leg (careful not to tight!) where the top of the boot will go. This allows the boot to move freely on the leg as needed. Put the boot on the dog. The rubber adheres to the tape on the leg extremely well. After the boot is on and stuck to the 3/4" strip of tape; the outside of the boot is taped (duct tape) from the top of the foot to the top of the "sticky side out" tape. When the two tapes adhere to each other the boot is not going to come off and no dirt or debris will get between the boot and the leg. The interior tape can be (and needs to be) somewhat loose as the dog's foot will not allow it to come off. NONE OF THE HAIR OR FOOT HAS ANY TAPE STUCK TO IT.
I use a pair of medical scissors to remove the tape and all 4 boots come off in less two minutes. The tape is then peeled off the boot and is ready for the next day. The entire removal process takes about 5 minutes per dog.
It's a bit hard to explain, but after running thousands of miles using the method, I've yet to have a dog lose a boot or have the hair rubbed away.
One note about dog boots, I've yet to find one that will turn away all cactus needles. When you know you'll be running though acres of prickly pair, I've taken a pair of welders gloves, cut them up to make a sole and used rubber cement to paste the sole to the bottom of the Lewis boot. You need to do this far in advance, so I usually keep a couple of sets with this modification in my trailer.
You guys that are using boots that use Velcro have my respect. They go on very fast and very easily. I am simply not smart enough to keep them on my dogs. My record time before losing one of those types of boots is 15 minutes. They usually come off, on or right after, the breakaway.
Lastly, motorcycle inner tubes work very well also. The main problem I have with those is getting them the right length. But I put them on just like I do the Lewis Dog Boots. Cheap, very available, effective, and a bit thicker than the Lewis boots. They keep the cactus out better but let in some debris.
Point!
