  • "I want to give a huge shout out to Dr Matt Schaefer with Dairyland Veterinary Service. I had been struggling to get weight on Kahlua. She wouldn't eat anything I put in front of her. Dr Matt came out and looked at her and we discussed her attitude and habits. He had a good feeling she had ulcers so he suggested treating her with ulcerguard. I got her on it and she is just 2 days from finishing the 28 day treatment. The change in her is phenomenal. She's put on weight and now looks perfect!
