All I can say is WOW. I work at a large veterinary teaching hospital and was introduced to Paw Friction from a coworker who is a certified rehab veterinary technician. My 12 year old Rottweiler has been having increasingly more issues since we moved into our new house almost two years ago. It’s the first house with almost all hardwood floors (only two rooms have carpet.) When she was standing, her back feet would literally slide out from under her and she was starting to slip and slide all over the place. I wanted to do something for her but was very unsure about dog boots (Would she even wear them? Would it cause dermatological issues from being closed off from air flow? Would she tolerate the sticky adhesive pads?) After discussing it with my coworker, she did a trial application for me and a week later, I bought my own package off Amazon. It gave her IMMEDIATE stability on smooth surfaces and she is even confident enough to trot on the hardwood in the house. Her first application lasted just over a week, through multiple walks and even a snow day in Georgia where she ran and played outside. I just did her second application tonight and put it on my other dog who is an 11.5 year old large breed mix. She has a lot of fur on her feet plus a previous injury that causes her paw pads to strike the ground incorrectly. She can’t sit without her front feet sliding out in front of her. She just sat down and was able to stay seated! I will definitely be keeping this on hand for the rest of their lives. It is extremely easy to apply and I only almost glued my fingers to their paws twice. They don’t even seem to notice it is on their paws Once I get the hang of it, I’m sure I’ll be able to apply it quickly and efficiently with no problems. And if you are careful and conservative, you’ll probably even get more applications that the box says. I DEFINITELY recommend this for anyone with a dog that has any sort of mobility issues on smooth surfaces.
