So, I've had a 16 year old horse on loan since the start of the year. All was well initially (apart from he's buddy sour and is tricky to hack alone, but I can deal with that). Recently, his personality has changed and he's become grumpy. I've had the vet out twice, on the last visit they've diagnosed equine asthma which may explain the change in behaviour. Going forward, WWYD regarging managing the illness? In the loan contract it states that the owner is to pay at least 50% of the vets bills (they have paid 50% so far which is great). Would I be unreasonable to ask them to put it through their insurance? as I need more medication for him and it's £100 a pop for two weeks worth! Obviously I've not been able to ride him, plus I've had to change from hay to haylage for all the horses as they share a bale. Advice/experience really appreciated! thank you xx
