I would rather you didn't comment on their weight. I know you mean well but...
Some of the pictures of Sinbad, where ones of him coming out of last winter (picture 3). He was dropping weight all through winter, and coming into spring, we really thought we were going to lose him.
He's well fed, he's fed Spillers Senior Conditioning Mix and Alpha Oil A chaff (both fatty, vit rich feeds). He's old (veterns do have trouble putting on and keeping weight just so you know) and he has regular check ups from the vet.
I know he's a bit of a skinny malinky, but he's a good weight now, and he has a thick rug for the winter, and of course, he'll be fed sugar beet and hay when it gets colder.
Barney, he was skinny when he came to us in April, but he's MUCH better now. He's laminitic, so during the summer, he had to be penned up during the day. He's put loads of weight on, now, and has a little pot belly.
You're right to be concerned, but their age is kind of an excuse, its hard keeping weight on a 32 year old and 40 something.
Sorry if I came across rude, I understand your concern. Their both happy, healthy boys.
Thanks for the comments guys.
