The first one is about rain rot, I'm assuming that's what this is:
What is the best way to treat this. I have a bottle of spray stuff called LympDyp or something. Is that a good option? Is it a problem if the rain rot is on an area of his back where the saddle will go? Is it going to be sore for him?
The second question is about weight.
Does he look like he needs to lose weight? A few people (non-horsey people) have made comments that he is fat looking. I never thought he looked large but now its been put in my head and wasn't sure anymore. What do you think?
