I'm glad you've found something affordable so that the poochies don't suffer. You might check at the pet stores in Johannesburg for dog food that had Glucosomine and Chondroitin (spelling?) That's what we feed our dogs since we have 15 of them and they play a lot. I have a friend that lives in Johannesburg too...she's my email pal and she has dogs so maybe she can give me some ideas where you might go and get food with that stuff in it. Good luck!!
