I have a 55 lb. boxer mix. He was a stray so i’m not sure of the exact age…but the vet had told me he’s probably 6 at the oldest. He’s always very active and full of energy–until last night. After going outside and coming back in he started acting like it hurt to walk, but it wasn’t a limp like he stepped on something. It’s almost like it’s his spine or something in his joints. I had to lift him up onto the bed that night and this morning when i took him out he just sat in the yard (after doing his business) and i had to carry him onto the deck and preceded to lift him back on the bed. He’s acting like he’s aged 10 years in 10 minutes! what’s wrong!! (I am a good owner- i have no intentions of neglecting his pain or whatever the issue may be, and i will take him to the vet if he isn’t better by tomorrow. Obviously the best answer here would be to seek professional help, but i’d like to wait at 24 hrs. to see if he gets any better. just looking for some advice or temporary fixes as of now)
