Hello,
I am a nail technician so my Rotty is used to them now lol.
Although once I did this really mad spiral nail, and was waving it in his face.....and He bit the end off
I was gutted, it took me ages to do lol.
It could definitely be the new smell of top coat, or oil applied,
It could even be because the surface is cold and smooth ...
Long nail enhancements however, are no good for rough play with rotties and their toys...Myself and many clients have found out as the nail pings across the room, leaving behind an immense amount of pain !!!
(plus the cost of a nail repair lol)
