<human>: So about 3 years ago me and my family(Parents/Sibs) received 2 male puppy German Shepherds, At the time they were very playful and happy dogs and i would spend a lot of time with them and such but as they got older one became very fearful of certain everyday objects like trash bags or cars and would act very aggressive towards that object, the other dog would tend to jump on most people and just try to prove its dominance it seemed, and it got to the point where neither of them would respond or walk beside you ect, so we got them training before it got way out of hand and it really helped, they stopped jumping and would stay calm and relaxed. But a few months later i got temporary medical induced lupus which took almost 2 years to go away and during that i didnt have the ability nor energy to spend time with them and walk/play/take care of them and the family members in my house would only spend around 10minutes a day with them and the rest of the time the dogs would be alone in the backyard. 
And the last couple months ive finally gotten better so i have been spending more time with the german shepherds but they have almost completely reverted back to their old ways as, they wont come when i call, they try and keep their distance from me when possible and dont seem to enjoy being petted, the fearful one wont let me take his toy and if i try anyway he will put his mouth over my hand or take the toy and run away from me. we also have 3 other older dogs that stay outside the fenced area where the german shepherds are and whenever one of the older dogs come to me while im outside of the fenced in area, the german shepherds will become extremely aggressive barking and jumping on the fence. 
So basically what im asking is how do i re-bond with these dogs and deal with their new aggressive behaviors?

Summarize the given text in a few sentences.
<bot>: Have 2 German Shepherds that i got 3 or so years ago, i got sick and couldnt spend time with them, now when i try to spend time with them they avoid me or act aggressive towards me.
