Appreicate the kind thoughts and suggestions, thank you all very much.
Dear old boy is 13 1/2 and has slowed down a lot, so in the twilight of his time with us. But Friday was a real shock as its very bad for retrievers if/when their back legs go completely and that is what it looked. Made it worse as I was going away for the weekend to see my sick mother and so we were in a bit of a pickle what to do.
But in the end, seems he was just very weak from being sick.mhe has been with in laws yesterday and today and they say that he is his normal, albeit old and slow, self
He takes turmeric every day BTW but good suggestion.
Again thanks for nice messages. Helped on a spookey Friday night/Sat morning.
