Wagtail
Horse servant
This is potentially a really stupid question - but are you 100% sure about her sire? If you hadn't told us her breeding I would have said she has a fair bit of native in there. Is it possible that there was an accident around covering time? It certainly would explain why she isn't as tall as her parents. As I said, probably a very stupid question and I hope I won't cause offence by asking it. She is a gorgeous little filly but I was just quite surprised at her breeding.
RE your question, as others have said, a lot can happen in six months, she might have a huge growth spurt and you may lose some weight. However, you don't sound too overweight at all. Make sure to get an accurate reading on a doctor's scales before starving yourself - your health is far more important than being able to back your girl, as much as we want to do these things ourselves.
Yes, absolutely certain of her sire. She has two other full siblings. She gets the buckskin (cream gene) from her sire. Her dam is brown. I know what you mean though as a couple of people have asked if she is Connemara.
I will get weighed at the doctors. I am not overweight, but definitely need to lose some for my little mare and I preferred being thinner. I felt much happier.
Ask if your local branch of Boots has a set of scales you can use. They are much more likely to be checked regularly.
When I was pregnant the doctors scales had me a whole stone heavier than the hospital's and a stone and a half heavier than mine. Eventually she bought new ones.
Heck that's a big difference!
