If its any comfort I have a yearling filly and a yearling colt, all through the winter they have been good as gold, yet since the first signs of spring approx 3 weeks ago its all change - filly is being stroppy and colt is very full of himself, bolshy, cheeky, difficult to lead etc so echo what...
I was shocked to learn that Iams who make cat and dog food
carry out cruel tests on on animals.

I had this problem with my dog, we tried Supadog Sensitive its not too expensive, and gluten free. Never had a problem since - lovely firm stools with not much odour .. hurrah!
