Yes, very important. However, I have to take our GSD to the vet every 4-6 weeks as she was a rescue and doesn't like this, it depends on the dog and how fast their nailz grow etc. If I had gotten her as a puppy I would clicker trained her to have it done at home. Hope this helps.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
