We recently purchased a four year old project filly who seems very depressed to me.
When I took her for a ride at the owners she was extremely quiet on the ground and just wanted you to hold her head, I'm not sure if that's her normal behavior but I'm guessing it is. She seems timid, not as if she is afraid but just a follower to the extreme.
When we picked her up she did not eat any hay in the trailer and has eaten very little since here (She hasn't been here long) she wont eat hay, nibbles at her grain but has not finished any, will not take treats, apples, carrots etc. She perks up and watches the other horses but is to shy to actually walk up to the fence line and meet anyone, she stays away. She is very obedient, thus far has been "perfect" and "to quiet". She did trot around and snort/show off a little tonight but still stays in her spot off to the side in the pasture. She's very responsive under saddle from what I saw and felt like she had go but from the ground she is to laid back. She just stands with her head in your arms or chest and closes her eyes.
This filly also has some conformation flaws that have me stumped, I'll be posting photos in the conformation critique tomorrow and would love input. She is a little thin right now so maybe this is part of it, maybe she's just a more sensitive horse? I'd say more time to settle will fix it however I didn't see much different behavior from her at the previous home.
Regardless, has anyone encountered depression with horses and what can be done? I haven't had much luck finding anything online.
