We adopted a GSD puppy mix about a month ago. He is now 2 and a half months and has learned to bark from our older dog. It's not aggressive, but he barks at her and when he is excited or trying to play.  We ignore him when he barks, and have tried using a spray bottle. However he loves the water.
A day ago we adopted a Great Pyrenees puppy who is 10 1/2 weeks. The GSD puppy now barks at her. He also tries to get her to play when she wants to chew a bone. She gets mad, then he gets upset and they start fighting. The GSD is also possesive of his toys. He's not aggressive, just takes them from her.
Another problem is he constantly wants to play with the other puppy and doesn't want to play with us or listen to commands. He's very smart and knows what we're asking, just gets caught up in playing. Any suggestions?

Two puppies at the same time is a very very difficult thing to do successfully. As you are already realising, they have a stronger bond than they usually do with their owners. I think that is your first & biggest mistake.

GSDs are gobby, this can be a plus or a minus depending on what you want the dog for.

They also love water so it is doubtful if spraying as a punishment will work.

Having two puppies with another older dog who is already teaching them bad habits is perhaps not the best idea?

GSDs are extremely playful and boisterous and having another puppy will increase the likelihood of the pups ignoring you because they can amuse themselves with each other.

GSDs also are quite possessive and do not really do sharing, but then again nor do many other breeds.

The problems you have identified will only increase with age...............

WUMs are out in force I see!

Ooh dear, you have a lot on your hands there! I wouldnt worry too much about the barking, sounds like he's just playing and having a good time.
However you are going to have to set strict boundarys having two pups at the same time its very difficult as like you say they are bonding with each other and not you!

Where did you adopt your 10 wk old pup from? They should have warned you about the consequences of having two pups together
Maybe you could ring them and ask for some advice

What are WUMs please? I'm slow on the take :)

Hi. I wouldnt worry too much at your GSD pup barking when he is exciting or wanting to play if its a high pitched bark. I have a GSD pup who also barks when she is playing or she is excited. However we have taught her if we tell her "enough" or "no" in a calm assertive voice, then it means she has to stop barking.

To train your pup to do this you need to get your pups attention when he is barking. Something that worked with us was a quick high toned ba ba ba ba ba ba. This should distract him long enough for him to focus his attention on your voice. Then tell him enough and call him over and when he comes give him praise and tell him good boy. If he goes to start again, tell him "enough" and if he doesnt pay attention again the high pitched ba ba ba ba ba. Sometimes it may be a case of going over to him if that doesnt work and crouching down for him to look at you and saying again in a firm but very calm voice enough and repeating this several times, making sure when he stops you give him a stroke, telling him in a calm voice "good boy" so he knows he has done right.

He is probably wanting to play with the new pup as its a novelty and a new play mate. A month probably hasnt been long enough for him to create a strong bond with you. I would suggest that you need to invest some one to one time with each dog or else they will become too "doggie" I have a CKC as well as my GSD pup and I spend one to one time with them every day on walks by walking them separatelyand creating a fun time so they know that its fun to play with me as well as one another. In the  mornings they are walked together, but the evenings they are walked separately. I think this is a must as GSDs can be very strong even as a teenager and there is nothing worse than having a dog who takes you for a walk. So by walking them separately at least once a day you are strengthening your bond with them as well as training them how to behave on the lead so there are no problems with pulling when they are older. Walking them separately will also give you a chance to practice recall, so there are no problems if you want to let them off, as it would be difficult letting 2 dogs off the lead if they havent mastered that particular command as well.

Re your GP pup who is 10/12 weeks. I would monitor them at play to ensure it doesnt get too out of hand and if it seems to be going that way, a ba ba ba ba noise aimed in their direction should be sufficient to catch their attention. If they carry on a stronger deeper "ba" does wonders and then telling them "enough" so they start understanding the word asssociation that it means to stop. Always make sure when you take them out, that you are first through the door and that they allow you to pass through the door way first. Both my CKC and GSD know that they have to sit at the door and  have to be calm before we will go out. Also coming back in they automatically sit and wait for me to call them in. It is important that they look to you as the pack leader as GSDs can be very stubborn, so you may need lots of repetition. They can be quite sensitive, so its important that you also give him lots of praise.

I hope this helps. Good luck with your new pups. xxx

As already highlighted two pups together is hard work, at least you have a male and female so heirarchy is already sorted the bitch pup will usually eventually take over.  The GSD pup will stay a pup for much longer though and want to play harder and probably need more of your attention, your PMD will most proberbly become more aggressive i.e snarling, teeth baring, to put him in order as time goes by.

You have two powerful dogs with different characters, you must train and work seperately with them, that is the most important key, this is the only way to get their attention as given a choice of you or another pup a dog will always choose it's own kind and age group of course, you have two babies who are going to get along, fall out, fight, sulk and then get along again, they will teach each other doggy manners but both are pups so will learn from each other awkwardly and sometimes a little hit and miss,so you will have to be their mentor as well as friend and trainer, you have taken on quite a lot with two pups, hope that you have the stamina and are ready for it. :-D

GSD pups are quite full on, so make sure he gets plenty of mental stimultion and play if he gets overly excited and barks a lot pop him in segregation for a few minutes to calm down, all pups grow into beautiful dogs as long as you use consistancy and of course praise and reward.

I expect that your PMD may find your GSD a bit of a naughty pest at times, stealing toys etc is a prime example, just make sure you have plenty of toys to go around, swap a toy your PMD wants and has had stolen with something else and a good boy, and make sure you have them in different rooms, sepertate walks etc for training and bonding with you their owner.

You have two beautiful dogs there please be patient with them both puppyhood especially in GSD's lasts a good 3 years with correct training you will have a dog of brilliant temperament who is calm and gets on well with the PMD, I would expect the adolescent years to be the hardest for you, just please you must have plenty of one on onetime and seperate walks and training to help mould both these dogs characterst, it will be twice as hard with two but if you are dedicated you will eventaully have two beautiful calm, well behaved dogs. :-)
