You can be any age as long as you understand how! I don't think a child under 3 could understand.
keep training till he gets it
The best time would be when your puppy is about 4 or 5 weeks old, or until the puppy is old enough to be away from its mother.
personally i think that Yorkie are easier to train. I have a Yorkie i got him when he was a puppy he pretty easy to train. but after they are about 6 or 7 years old they are really hard to train.
No. With consistency and proper training methods, tools and rewards, a 3 year old dog is sometimes easier to train than a puppy.
Nope your dogs still a puppy kinda. You can still train your dog.
You should take your puppy out at least every hour, if it's a male puppy they need to go more often that a female puppy or so seems anyway.
Play with her and pet her. And train her. I began to train my two six week pups to sit and come when they were called and they caught on fast!
you must bring somebody to train the dog for the child
get it a puppy pad & train it on that
Good Luck!
Teach it to 'stay'.
train him to come
