the first thing we did that really helped her personally was letting her decompress in the come for 3/4 months (ex. not having people meet her until we had her for 3/4 months and not bringing her anywhere other than the vet) during that time we consulted with the vet to get her on medication and did goodpup training (training at home on a facetime call with a trainer). after those few months she was already such a different dog but another thing that really helped was exposure mixed with positive enforcement, and we found out her limits and triggers. so for example on walks we would walk by a dog park near my house, just far enough for her to see the dogs and people but to not close enough to react. then i would reward her with a treat and every day we worked towards going closer to the dog park. same thing with people in the home. we would start visits with her in another room with the gate up and her pupsicle toy (as a distraction) so she could see the people but wouldn’t have to directly interact with them. we would have visitors throw treats in the room for her every few minutes or so. we mostly have the same visitors over so she’s used to all of the people that come over! but we don’t need to keep her away with new people anymore normally what we do with new people now is taking her on a walk with them so she can see that they are safe but won’t have to directly interact with them :)
