In a side note, I got ahold of my local vet this morning and he said "let's talk about this in better weather...how about just call me tomorrow or Saturday...we'll go ahead and try to do it that day (if the weather's better)".
Strange old man!!!!! ;)
I interpret that to mean, he wants the colt outside so he can move around after being gelded and nice weather is important for that.
Down thru the years, all my stallions were gelded outside and every vet said to make sure they move around.
The only one that wouldn't exercise himself, is the one that swelled up like so many helium balloons. The vet had to come back out, sedate him and lance him. THAT was a fun time - not
What a great update
If the aspirin is powder form, cut the tip off a 60 CC syringe, put a bit of apple juice in some water, mix it up and hopefully he will let you syringe it down him
If the aspirin is in granulated form, that won't work because the granules won't mix into the liquid like powder does.
On the other hand, it might be best to not relieve his pain so he doesn't do something stupid or risk getting ulcers, given the condition he's in.
If the vet does the cut and snip this weekend, he will examine The Lad and probably give you something for him
I hope the weather holds for you
