You should begin training as soon as the puppy is home.
Tiara is 13 weeks old, she knows the sit, stay, come, leave it, down, roll over and bang!! your dead trick.
They are like little sponges I tell ya. I keep it short and sweet maybe 5 small treats twice a day. She will do it on call with a treat 100% of the time. She is a bit slower without a treat but I just praise the heck out of her. Slowly giving her less treats for simple commands and more praise.
I'm trying more intricate tricks but I think she is still too young.
Oh, I forgot, she also does give me five! and High Five.....she is so smart!! It kills me.
Just work at it everyday, a couple times a day. We taught our friends Boxer puppy to sit in one night at the house. Now he sits all the time when told. Its very easy if you just find out what motivates them. Is it treats, praise or toys.
Good Luck to ya!
