The dog I'm worried about right now is Nacho, our 2yr old Boston terrier mix (beagle we think). He's always very playful, smart, loving and sneaky. (Especially compared to our 7 yr old golden retriever). He normally is a troublemaker however, recently it has been more so. He ran through 3 electric fences to follow me when I left on bike the other day. He had run through the electric fences in the house, but never the one outside. Next, Nacho peed all over the couch and floor. He has not had an "accident" for at least 8 months. Lastly, at 11pm I walked past nachos crate where he began to wine. This is very normal. I decided to sit with him for a bit and so I let him out. However, nacho refused to leave his crate which he hates. He also wouldn't let me shut the gate again either. I finally reached in and picked him up. He was calm and sleepy and shaking inseaintly. I got blankets in case he was cold but he still was shaking as if he were terrified. I understand these aren't major synmtoms, however I do not want to over look something. If you have any idea why he may be suddenly acting this way please lmk.
