6 months sounds bonkers! I’d ring the practice and ask for a second opinion, tbh.
We have had our first trip to the woods today! We only did a very short meander, with lots of stops, but Spudpup met some dogs and children, and saw bikes and pushchairs. Then we had a coffee at the coffee shop (it’s a Forest Holidays place) and watched the world go by.
He has come home, eaten lunch, and collapsed in a heap behind the kitchen chair 
This afternoon we are going to meet up with my friend so he can see horses, cows and farm machinery! He’s going to be comatose this evening (I hope)
