Nipping/Toys

I am a new basset owner, and very excited about my little patito (tito for short). I am a little worried that the breeder I got him from lied when he told me patito is eight weeks old because he seems so small to me...does anyone remember what there puppies wieghed when they first got them?

Also he is a nipper I say ow and give him one of his toys but he doesnt really like any of his toys normally he rejects that and trys to nip me again. Any suggestions?

Thanks!
