I know that when Lola gets an upset tummy, she tends to whine and doesn't like being picked up. Maybe that could've been the problem?? I think it might also be a little sprain somewhere or something?? The vet will be able to figure it out. If I were you, I would just closely monitor my little one and if he starts acting like it again, I would take him to the pet emergency. Otherwise, probably tomorrow will be fine. Good luck
I hope it all works out (I'm sure it will thought
)
