Glad I've come across this thread. The picture in the first post is exactly what my Chance looks like. I didn't take a picture of him as I thought it wouldn't show up well enough. Chance has a few more bumps though.
It started on Saturday night. I called my Nakura's breeder and while I was talking to her you could actually see more lumps appearing. I gave him half a Loratadine tablet that night. On Sunday morning the lumps had gone. PHEW!
Sunday night, they had reappeared! Worse! I gave him some arnica and by now we had a supply of Benadryl. We gave him a Benadryl and kept an eye on him. On Monday morning the lumps were almost gone but not quite. I then got some Apes Mel 30c and started giving him 2 tabs every 2 hours. This seemed to keep them at bay.
He had more lumps by lunchtime so we took him to the vets yesterday as we were worried and were told to keep up the Benadryl for a few days and go back if it hadn't cleared up.
This morning he has woken up with lumps all down his forechest and tummy. I've given him another Benadryl and some Urtica Urens spray.
We don't know what has caused these hives but suspect maybe nettles as our garden is full of them or possibly midges! We've not changed anything in his food so are pretty confident it's not that.
I think I will go back to giving Loratadine as it seemed to have a greater effect on the lumps.
Douglas has paid ?400 for a new industrial strength strimmer so we can get rid of all the nasty nettles and tall grasses in the garden!
I feel so sorry for Chance he looks awful and has scratched his armpits red raw. Hopefully it will clear up enough by the weekend as we are travelling a long way for a Breed Champ Show.
I'll keep you posted as to how he gets on.
