Extreme behavioural change
Hi following numerous vet tests / behavioural assessments I'm hoping some one out there will be able to shed some light or provide some direction I can take with my mare. 'Leyla' is a three year old warmblood / thoroubred cross ; several months ago I notice that she had large swelling near her gland (right side under her throat). I had her scoped and it was identified that she had a small bit of timber lodged in her guttural pouch which was causing the gland to swell (vet stated it was infection), we placed her on anti biotic's for several weeks, however the only thing that changed has been her behaviour. She has gone from a sweet natured girl to laying her ears back, charging at me, rearing and striking, last week she threw me for the first time and fractured three of my vertebrae's; even when I put her rug on she goes rigid and lays her ears back ready to attack. My neighbour had even stated that whilst she was working near the fence, 'Leyla' came charging across the paddock towards her and with her teeth bared.
There has been no changes to her diet / stable environment or daily routine. I've had blood tests conducted which have all come back clear / teeth has been checked/ chiropractor has seen her , all in all I believe I have covered every base and have now hit a brick wall.
This mare has been with me since she was a baby and as previously stated she has never been a problem. If any one could provide some direction or advise it would be greatly appreciated. I won't get rid of her as I feel there is a 'medical' problem causing this extreme behavioural change, just knowing what that is or how to identify the problem has me stumped.
