Interesting. I wonder if there's been any link to peanuts like the macadamia.
Awhile back, I gave our dog a peanut & he was acting up & not feeling good. I thought just (1) peanut should have not made him feel ill. Anyways, he puked (a bunch of bile) with one little peanut i the middle. Right after that, he was 100%.
Last tuesday I was up late & having a few peanuts. He was begging like he always does & I gave him a 'few'. The next morning, he couldn't stand on his left front leg. He was hobbling around like an old man all day & would just sleep. He showed no interest in anything but he did force himself to get up when it was time to eat.
The following day...he was 90% better & the day after that...he acted like there was noooo problem ever.
So...now I am thinking he may be highly allergic to peanuts. His sister shows no signs when I gave her some too.
