Some days ago my wife and i get a 2 months old pinscher puppy(Lucho), and this is the problems we had so far.
- We have a dog called Princess that is 10 years old and every time lucho try to play with her she tries to bite him, and my wife is kind of worried that she kill him.
- Every time we feed Lucho and take him outside to make his job we can wait all night and he does nothing but sniffing, but as soon as we get him inside the house he make his trick and is cleanning time for us.
- How we can teach him not to bite our shoes and our hands and feets, because everytime we catch him doing it we say "NO" and give him a toy to bite, but he just smell it and leave it and look for another shoes to bite.

Can anybody give me some ideas.

Thanks
