Diddy arrived with us at the end of August (our second Fjord pony), and about 3 weeks ago we noticed that the lymph nodes under her jaw were slightly swollen. Not visually swollen, just by feel, compared to the other horses. They about the size of a good marble, and she doesn't mind if we touch them. They aren't near the base of her neck, more halfway down her jaw between her two jaw bones going down towards the underside of her bottom lip - if that makes sense. I can't really feel the other horses at all in comparison. She is fine in herself, eating and galloping in the field and hacking out happily. The other 3 ponies are fine and nobody seems unwell.
Our vet is due out in a couple of weeks to do Merry's vaccinations, so we will ask his opinion then. We she arrived with us, she was quite itchy and scratchy and she rubbed some of the hair off her face in places. The vet looked at it and took some skin scrapings away for a further look but didn't find anything, so told us just to give it a wash with Hibiscrub, and the hair is now growing back. We are not sure if her glands were like this when she arrived or if they have flared up since she came here.
Having had a look online, a lot of people have said that it could be grass glands - never heard of this before, or that some horses are just put together this way and it is in some cases just fluid.
Anyone have any ideas, as it is a worry to Mum as it is her horse. :(
