Bulldogs World

I seem to have a behavior issue on my hands and am hoping someone here has some experience with something like this and may have an answer. First some history:

We got Sissy around the end of March last year. She was 4 and a half years old, had previously been bred, and was spayed by her breeder about a week or two before we took her home. When we brought her home I pretty much had to hand feed her the first couple days to get her to eat and then after trying a couple different foods we finally got her eating normally again. Sissy seemed to bond with me pretty quickly and accepted the other members of our household, eventually including the cats even. She has always been very affectionate and warms right up to anyone who comes into our house. For the most part her behavior has always been relatively normal for a Bulldog (in my opinion anyhow).

My concern is that she has always been very sensitive and at times even fearful. When we brought her home, she was terrified of silverware. Now I know you're not "supposed" to feed dogs at the table, but I'll admit I'm guilty of sneaking a tablescrap to anyone patient enough to wait on the floor in the kitchen. I've never had a dog literally back away from a spoonful of peanut butter before but it took months of coaxing to get Sissy to lick a spoon. She has always been very bothered by any type of yelling, whether it's my husband yelling at a video game or our 6 year old daughter throwing a tantrum, she is very upset by it and will cower in a corner. She's even run upstairs and left her dinner before during one of our daughter's tantrums. Sometimes she will bark at my husband for yelling at something and I have scolded her for this behavior and this may stop her temporarily but the next time it happens she will usually bark again. About a week or two ago I allowed her onto our bed in the morning for a few min before I got up. Nobody was yelling or anything and then later that night my husband found a wet spot on the bed. Since we didnt catch anyone in the act, we had no idea who did it. But then tonight, Sissy urinated on her usual spot to lay in on the couch in reaction to someone shouting. I just had her in the vet about a week ago for an infection in her leg which she is currently on antibiotics for but otherwise she was deemed healthy and since these incidents have been so far apart, I wouldn't think she has a UTI. (she doesn't seem to be going out anymore frequently than usual either) So I can only assume this is behavioral with her. I'm really at a loss as to what to do. We have never hit her and because she is so sensitive, nobody is yelling at her, but I really have no way of knowing how she was treated before we got her.

She seems to have a few emotional issues because my vet has suggested that her constant licking could be OCD and the best suggestion the behaviorist had for that one was feeding her meals out of a kong. (as long as we've had her, Sissy has never been interested in any of the toys we've given her for more than a few min, including ones with food in them) I've never adopted an adult dog before so I've never been through anything like this. Anyone have any suggestions? Eliminating any and all yelling in our home is pretty much impossible (as any of you with kids probably are aware) so there has to be something I can do to help her feel more secure. Thank you all so much in advance!
