Afraid to go outside
Hey, I know I haven't been on here much but I could use some serious advice. for quick background, Nova is a kai ken about 1 3/4 year old. she typically is pretty hesitant to meet new dogs and sometimes aggressive when they get in her face so for the most part we simply avoid dogs on our walks and play a lot with humans which is fine by me. my brother also has a dog, labradoodle and about 60 lbs (nova is 30). typically I don't like them hanging out even though they seem to get along really well. Saturday the dog came over and nova was loving it, they were running around, everything going great. a few hours in nova is hiding by the backdoor wanting to go inside so I let her in not thinking much of it and she scurries inside. I go back to get her after about twenty minutes but shes hiding in her crate and will absolutely not leave it. again not thinking too much of it I just leave her in her crate with the door open and go about the day. eventually I just grab her and bring her outside to hangout and she sits right next to me the entire time and seems anxious but not unlike other times when ive seen her anxious and cuddly. the next morning we go for a walk and shes pretty hesitant at first but once we get about 100 ft from our house she breaks into her normal self. we see another dog on the walk and she tries to start running but pulls up her right hind leg in obvious pain and I carry her home after seeing if she could relatively walk or had a splinter or something. so the vet thinks she probably just has a sprain or something and we have pain meds now BUT she will not go outside and will not go to the bathroom or eat or drink hardly at all. she has peed like once a day the past two days and pooped once only after I noticed that she was actually slowly pooping inside the house simply from not going in two days and she very reluctantly stood in place in the neighbors yard, pooped and walked the couple feet over to me and sat down and just looked at me nervously. the pain seems to not be a huge problem as I initially thought, but I have no idea what happened between her and the other dog. at no point did I hear a yelp or notice anything problematic that day and I was watching pretyy closely. im pretty sure the other dog probably just jumped on her or something and while im obviously not very happy she got hurt im much more concerned with her extreme fear right now? any suggestions or similar experiences people have? I know kai are sensitive but shes never acted like this.
