Paranoid behavior in Black Lab/Terrier mix
melann53 posted:
I ran across several posts from 2-3 years ago that sound nearly identical to what my 81/2-year-old Black Lab/Terrier mix suddenly started experiencing about a month ago. I returned home from work and my dogs stay outside during the day and inside at night and on weekends. This particular evening, I heard Serena whining which was totally out of character for her. I pulled in the garage and opened my vehicle's door and she jumped in my lap acting "scared to death". Once we got upstairs, her back haunches shook for at least 10 minutes. I was completely baffled by this behavior, as we got her as a pup and she had NEVER behaved this way. I assumed something or someone had scared her in some way, but had no idea who, what, or how! So, the next few days, I let her stay indoors while I was at work. She would go outside and "do her business" and come rushing back to the door to be let in. Unfortunately, the behavior has worsened over time. Now, the only way I can get her outside is with a leash. Keep in mind this dog has ALWAYS loved the outdoors and was the first to the door to be let out. I took her to the vet b/c she has a large cyst on her back foot and thought possibly she was reacting to it being painful. The vet was unable to get any cells out of it and very little fluid. When I explained her behavior to him, he thought it might be arthritis in her hips and gave me medication (we did notice after this vet visit that she yelped when she started running, so we thought the vet had diagnosed her properly). Within the first week, the medication appeared to help until it wore off. Now, even the medication doesn't seem to help her. She walks w/her tail tucked between her legs and her eyes look like she is scared. There are even times when she will suddenly take off like something has bit her!! She stays close by my side, so much so that's she is underfoot. I honestly have no clue how to help her!! It's times like these I wish my animals could talk to me. If I could only figure out what is causing her angst and sometimes panic, then maybe I would be able to find a solution to help her. If anyone else has run into this same problem and found a remedy, PLEASE let me know. Thank you for your help!

I have a 6 yr old female Shih Tzu that just in the last couple of days has had very similar symptoms, when any other day can't wait (literally)) to go outside to bark at anything.....the squirrels, the wind.....Now all of a sudden, visitors that come to my door whom she had loved to greet jumping and barking without fail, can knock and walk in and she remains quiet and lying in her bed. Can't and won't jump up onto the couch, or up steps to come into the house. She hasn't yelped in any pain or anything as yet, but from researching in the last days here, I believe that she may be displaying symptoms of Disc Dysplaysa and am taking Suzy in tomorrow to see the vet, and I encourage you to do the same, if you haven't already. And, I also encourage you to read anything and everything online on this topic. Best of luck to you and yours.

Thanks for your reply. I have already taken her to my vet. He said he doesn't deal with behavior disorders.
