I adopted a terrier mix and was told by the foster home that she came from an abuse and neglect background— living in a car from birth with 4 other dogs. All 5 dogs were recommended to be euthanized by the city animal shelter because of their severe PTSD and aggression. A rescue group adopted them all and placed them in foster homes. I have now had her for 2 years and she clearly has very severe PTSD. I have tried everything training-wise to mitigate it to no avail. She is very skittish around strangers and even people she’s met before. She will bark and run at house guests, even having bitten a few people. If someone in public even glances at her she will bark and make an attempt to attack. We have another rescue dog who she gets along with very well, but any other strange dog she immediately will attack and bark at, even if the dog is docile and uninterested in her. If we talk loud in our home she cowers, even if we aren’t raising our voices at or around her any loud noises or voices cause her to become fearful and guilty. If our other dog does something naughty she will hide as if she’s guilty by association. We have never once laid a hand on her and do not yell at her ever- but she acts as though she is going to be beaten. It is very heart breaking to watch, as she is a very kind and gentle dog towards my husband and I, and our other rescue dog. I’m unsure how bad her previous situation was, but it must’ve been horrible. I am 8 months pregnant currently and am very concerned about her barking and attacking behavior, as I am afraid she say bite our baby. She has lunged at small children multiple times before. I am unsure if I need to take her in for serious professional training or if I need to just put her on the dog form of Xanax to sedate her. I would prefer to not have to medicate her and allow her to live her life unsedated, but she seems so chronically stressed.
