Familiarity: I've used it several times
i bought these because my dogs pads would get tore up on longer mountain bike rides. it took a few times for her to get used to them, but no real problems. i first put on just the just the front paws, rewarded her and let her walk around a little. then i took them off and put on just the back ones. reward and walk around. build it up like this and by the time i put on all four she didnt walk funny or anything, much to the disappointment of the internet. they stay on well when the velcro strap is set. i did have to trim her nails shorter because they were crowding the front. all in all they are worth it, she can last a lot longer on trails and i dont feel bad about having her on hot pavement.
