I have a 14 year old GSD that struggles on our wood floors. She has arthritic paws that cause her to walk on her nails a bit as well, which certainly doesn't help. I assumed these would be a waste of money but I was so so wrong! After throwing these suckers on, she was running around like a maniac in the house. The second time I used them, I cut the pads out and stuck them on intividually and it was like she had brand new paws. In and out of the house they stay on and stay pretty clean. What an outstanding product!Pretty good product I ordered a medium forMy 5 month old micro bully’s and it was too small luckily it fit my nieces chihuahuaThese work perfectly, helps our 12yo pitbull stability coming down our wood stairs..A must if your dog slips in floors!!Easy to put on and they stay on him for a few days. We do keep his paws very clean and use a pet wipe each time he goes outside. We also keep the hair between the paws and nails trimmed. I will hold my hand around his paw for a couple of minutes to make the tape warm so it adheres better.Both of my dogs are very active they run up and down the carpeted stairs the pads came off within days.They didn't work.These were great while they lasted on his paws. I did the cut apart method and they all fell offing less than 24 hours.After a fight with a German shepherd to get a set of these on I was hoping they would last more than a day. Before the first night was over I was picking up pieces scattered through the house. They did help her walk better for the bit of time they stayed on though. I was hoping to get at least a week out of each set since she hates her paws touched. It wasn’t worth stressing her to put them on again
