Kola is my sensitive girl. I've learned over the nearly two years I've had her within my company that she is very sensitive. She tends to stress colic with bad storms in combination with heat cycles and I'm now getting better at detecting it and intervening with a dose of pro-bio and banamine. She also has been lower on the totem poll. Misty has always been alpha, however lately the table seems to be turning which surprises me. I've noticed this week, that perhaps Kola is tired of being nipped at and is aggressing the nips now at Misty. Maybe that is why Misty has been more evasive of me than she has ever been. Also Misty's attitude is a little bit different lately. She seems to be a bit bent out of shape. I think where Kola stresses, it comes out physically and Misty stresses, she takes it out in attitude. On a good note, I also noticed that the for the first time in nearly two years of the two of them being together they were joined in a display of I'll groom you if you groom me. Interesting horse behavior. When they came down with the "slobbers", it was Kola who really suffered and needed the attention rather than Misty. Steve keeps saying, "Kola really has a sensitive tummy!". So which of yours is most sensitive and how does it play out? Do you know about it ? Do you have to intervene with supplements or drugs?
