Welcome MJ!!! Oh, your Havana is such a cutie! My Lab Star often sports that same "nose"

The oil could be upsetting her stomach, especially as she's not accustomed to it. I'd start slowly, perhaps adding just a teaspoon once per day for a week, then increasing to two. Did the vet say 1 tsp. per 25 lbs? That would make it a total of 2 tsp. daily? Correct me if I'm ,osreadomg, but I think you're giving her a total of 4 teaspoons daily? (2 at each meal?) Might be a bit much for her. My girl is 54 lbs and I give her just one tsp. per day.

Feel better soon, sweetheart! Hope to see lots more of adorable you!

I'm Sandra and my girls are Star and Cody, a yellow Lab and Husky x!
