A worry...

Hey everyone. I'm afraid that Blue is a bit ill at the moment. He has gone from overweight to underweight in around 2 weeks! This significant weight loss has created a bit of concern and our trusted vet is coming around tomorrow. I have been riding him and he has stayed perfecto, really keen, galloping, jumping and has no problems with the bit. He hasn't changed his eating patterns, pooping patterns or field behavior. Shannon, although skinny is in fine health and had has no significant weight loss or change in shape. This rules out all the ideas of contagious disease and makes parasitic infection unlikely. I have now stopped any hard work completely for the main reason that he is just going to lose more weight, which for once isn't wanted. The way the fat has left the body is strange, disappearing from bum and ribs but staying around stomach and chest. This may just be the way fat is distributed around his body, highlands are known to put weight on in their stomach and chest so maybe the first to go is the other areas. He also has a reasonable indented hip bone, again showing a loss of weight in rib and bum areas. This is a little alarming, all in all, he seems his usual self so I really am at a loss as to why his losing this weight. If anyone has an idea on why this is happening feel free to email me at bluehoofprints@gmail.com. Thank-you and I apologize for a lack of videos as Blue obviously isn't up to anything now.
