The first thing I tell anyone that gets a new dog or puppyis to get get and Keep them used to having their feet touched and held!!

Sierra was about 6 months old when I got her and I started right away but had no problem with her, she's very calm about a lot of things. Buddy was already a year old and I doubt he'd ever had his nails cut, it took quite a while to get him to let me cut his nails but now it's not a deal a all!
I (Try to ) cut their nails every 2 weeks or so.

Just work in baby steps with your pup, a little at a time.
Also, "special" nail triming toys or treats work well too! My sister gives her husky a kong that is only given to her while her nails are being trimmed.
Make it a Happy Time!!
