Dog Owners: a little advice please:)  

How are she and the Dad interacting? Do they get along, play, scuffle?

It's good to let them play together, but be aware of the energy in the playing. Does it get too heightened? Then step in if you feel you need to. My brother has a new puppy as well - he's about 8 months now. He likes to play with all the other dogs in our family and be too aggressive. He's a bigger dog, one of our family dogs is very small. We used to step in and pick up the small dog so he couldn't hurt her, but found that leaving her alone worked even better. She would snarl at him, and he would back away, never biting her. Now he lets her be - and she's not fearful of him. When we were stepping in, she would be afraid.

I would also recommend to you to watch The Dog Whisperer on National Geographic Channel. Although he isn't working directly with puppies, he has very good advice on dog training. Animal Planet also has some great dog shows - and some of them I think are specifically about puppies. One that is great for training, but isn't puppy directed is It's Me or the Dog. She's British, very fun to watch.

NEVER hit your dog or puppy. Always be aware they are behaving as they do for a reason. They need to know you are the alpha of the house as they are pack animals and look for a leader - if they don't have one, they will become the leader and that has nasty behaviors. You don't have to be unkind, but let them know what is ok in the house and outside and what isn't. Teach them to sit for their food, preferably after having a walk - dogs like to "work" for their food. Walk your puppy every day - a couple times a day. If she's not used to walking on a leash, she may take some time to get used to it.

One thing I've seen others do and it works - to get your puppy to not be a dog who runs away when off leash - play with them outside: hide on your puppy - or keep moving out of sight, training them always to look for you. The best thing you can do for your dog as a puppy is to teach them to look to you for what you want from them. IE: getting on furniture, eating, sitting, smelling other dogs, etc. Teach them how your pack works. Your older dog is the leader of the "dog pack" and that's partly what Dad will be doing too.

Do you have any specific questions about how they are together, or your puppy's behavior?

keep the pup confined to 1 or 2 rooms until he knows where to pee and do his business. you could also put newspaper down, or those house breaking pads. after he does his business immediatly take him outside ( her ) . a word of warning NEVER give a dog grapes, raisins, garlic,onions or chocolate it will destroy the dogs kidneys and pancreas in months, again NO GRAPES,RAISINS, ONIONS GARLIC, OR CHOCOLATE, OR ANY SUGAR FREE SUGAR HE MIGHT GET FROM EATING A PEICE OF SUGARLESS GUM THAT FELL ON THE FLOOR OR SUGAR PACKS THAT ARE SUGAR FREE. HAVE HE MEET HER DAD IN INTERVALE UNTIL THE OLDER DOG GET'S USE TO HER, BUT I WOULD ASK A VET ABOUT THAT JUST TO MAKE SURE. I DONT THINK THE OLDER WILL SEE HER A A THREAT TO HIS HOME ALTHOUGH HE WILL MOST LIKELY LET HER KNOW HE'S THE ALPHA DOG IN THAT HOUSE. CUTE PUP BY THE WAY
