Question about "filling out" a TB mix
I always thought I would be the owner of a QH or maybe a TWH...but as we all know, sometimes the right horse for us ends up being a breed of horse we never thought we would own.
I purchased an Argentinian Polo Pony (The Pony part makes me laugh because she is 15 hh) at the end of January. She is not registered but most polo ponies are TB mixes and the vet paperwork I received has her listed as a TB. She has been at my boarding facility since Feb. 4.
When I first saw her, she was underweight. Since she was moved to her new home, she has gained a considerable amount of weight and I am working on building muscle as well.
Since I am clueless about TB and their weight issues, I was wondering if it is normal for them to "fill out" in the rib area first. As you can see from the pics I am posting, she is filling out nicely there and is not as ribby. But her hips are still pretty bony. Can I expect her hips to stay that way (Is that a TB thing?) or will they fill out as well as she continues to gain some weight and muscle?
I am sorry if this is a stupid question and I will be asking my trainer and BO as well, but thought I would post here because I have been wondering.
