my german shepard is very jealous of my new adition called boysie, he is a 11month old shar pei. she is only 16months. wot can i do?

Send the shar-pei back to where you got it from..

sorry to sound harsh but your girl is only a youngster herself and needs to grow up mentally first before introducing another dog into your home. I think the best age for bringing in a new dog is when the oldest one is over the age of 3 then they are adults mentally themselves and have the capacity to be more patient with a young 11 month old newcomer.

You basically have 2 juveniles now that will squabble over you-toys-food everything. Walking them regularly together might instill a more of a pack bond. Is there a dog training centre near you? you would benefit from taking them both to dog training classes for a more harmonious home life, as you train them to listen and behave when situations do arise you will cope with them better. It is not going to be easy though.

If you do persevere... best of luck.

i think it would of been better to wait a bit longer before getting your second dog but saying that depending on the dog it is possible to make this work with a lot of hard work on your part.
i would take them to training classes but not at the same time, so you get each dogs full attention. it will not be easy to have them both with you for this.
i would also do a combination of walking them together so they build up a bond but also you will need to walk them at different times so you can get their full attention and train them better.
make sure you never leave them a lone together in case things get out of hand, they are only young and need to learn boundaries and acceptable behaviour.
both dogs need to learn basic commands so you can control them and they listen to you not each other.
if one gets over excited use distraction by calling them and making them sit for a treat or toy. if they want calm down then say nothing but remove which ever one it is out of the room to a quiet place until things are calmer.
you really need to spend a lot of time exercising and training both dogs so they use their energy in a constructive way and not on each other. tired dogs are less likely to be silly around each other as they feel a lot calmer.
i would start by giving them plenty of time apart and small amounts together until they are used to each other. try not to give them too much attention apart from training and walks so they learn that there is certain times when they are expected to be calm. it would be a good idea to put dog gates up so they can see each other but not get too one another if needed.
there's not a lot else i can say apart from unless your prepared to put in 101 per cent into this then there's a chance it may not work. some dogs never except a new dog into their home. you need to make sure they respect you as boss, always stay calm but be firm and make sure they know the boundaries.
good luck i hope it works out for you.
