Thanks all for your continued support!
To answer a few questions, and an update.....
1. It seems that Jersey might not be 7, but according to an instructor who looked at her teeth today, "in her teens." Maybe I heard wrong- perhaps my daughter's trainer said "17" and not "7." Is that too old?
2. This instructor also said she would be sad to lose Jersey as a lesson horse, as she is "so perfect." That's a good sign :)
3. My daughter was riding Jersey 2x a week over the past year, and others were definitely riding. She was probably getting ridden 5 or 6 times a week. The owner told us that more recently she only had one child riding Jersey - so perhaps she was only getting ridden once a week. My daughter said that she could tell Jersey was out of practice as she had "forgotten how to canter." I'm sure she didn't "forget" lol, but it doesn't seem that not much was being asked of Jersey recently.
I am feeling more confident that it is a good decision to buy - so I'll set up a prepurchase vet exam. In an effort to get my daughter more involved in the process, and to understand the gravity of buying a horse, I had her put together a list of questions (with my help) that she would want to know from the owner (her trainer). These include:
1. How long have you owned, Jersey, where do you buy her from, and do you know her history?
2. Is she registered?
3. Any conformation flaws?
4. How old is Jersey?
5. Has she ever had colic, illness, or injury?
6. Has she ever been shown. What are her competition results?
7. Does she load easily?
8. What feed and supplements is she on now?
9. Does Jersey require corrective shoes?
10. Has she ever had laminitis or been lame?
Is this a reasonable list? I thought it was pretty good for an 8 year old:)
