Hi Kathleen - I have a "Scarlet" also!!
She's half sister to my Ashe, who i've had as a puppy.
They both had stomach issues a few weeks ago. Vet said to give them pepcid also. But the best thing is they were eating home cooked meals for a few weeks now and everyone is doing so much better. I've been treasuring this time not only because everyone is doing well, but because I don't have to hold my breath everytime I open a can of dog food wondering if it's going to be recalled.
Unfortunately, my cooking isn't a balanced diet(I don't know how to do that) so I'm slooowly introducing canned food back again.
I'm hoping everything goes well. But they sure bounced back with home cooked food & they loved it.
Hope your Scarlett continues to get better also.
