We're back from the vet, Momo is ok, Thank you!
It appears that he did get stung by something (right rear paw) but no stinger was found so not sure by what. He might have licked it off or something...he's walking & acting normal now. He got a benedryl shot & a steroid shot. Now I need to drop by target & get some benedryl pills bc he hates the cherry flavored children's liquid version.
He scared me so bad bc @ home, he was shaking his leg, kept trying to lick it, not putting weight on the right hind leg, acting drowsy (couldn't be from the 1ml of liquid benedryl
bc he's 5#'s & he needs 5mg/ 2.4ml), throwing up white foamy liquid & a lot of it...I thought he was going into anaphylactic shock. The bugger was alert & attentive @ the vet, trying to smell other dogs & wagging his tail.
loll
Vet said he could've been in shock from the insect sting & the yucky taste of the benedryl made him throw up.
