HA! When you find a solution you will be a millionaire :-)
Some things that help:
-- area rugs with non slip backing
-- keeping nails trim and short as possible
-- keeping paw pad for trimmed for less slippage
We have pretty much failed in this area--there's only so many rugs you can use before you feel like you might as well have carpet ;-) Our biggest trouble is mealtime, Rosco gets so excited that he flies to the house to get to his bowl and comes back to where I am in the food area and then runs back to his bowl--he usually tries to balance from rug to rug but sometimes I hear those nails!!!
I don't know if this will you help much.....
Our friends had new hardwood floors installed about a year and a half ago. When they bought it they were told that it has a varnish that will protect the floors from nails, chips and stains. I was just over there last week and asked if she was happy with her flooring. She is thrilled, no marks, stains or scratches. She has 5 dogs so has certainly put the floors to the test. If new flooring can come with this, I would imagine that you buy the varnish someplace.
Wow! Do you know what the varnish is called? Oski has such poor traction that he can't even sit on wood floors--he sits with his knees pointed inwards & still starts sliding, lol
Show foot?! Hmm. I might need to get that for after Atticus has his surgery and shouldn't be allowed to slip or slide on our floors. Thanks for mentioning that, Connie. I'm off to Google it.
We have four doodles in our home & hardwood floors on the first floor. Adina's advice is spot-on and that strategy has worked well to keep our floors looking good. The latest tool we've found that works to make nail trimming better is the Peticure Pro. It's lightweight and makes less noise than other models. It took the dogs some time to get used to it, but it makes the job much easier and nearly eliminates the chance for injury when trimming. After a trim with the tool, we buff the nail with a (for humans) nail buffer to smooth the edges (thanks to Kate Pappas for the tip on the tool & the buffer!). Good luck!
