Sadie update...
Here's the last response from my asking how Sadie was doing:
Hey there. Everything is going well. Sadie has reverted a little bit being very skiddish. I can’t figure out if she hears a dog barking in the neighborhood or what it is that sets her off. Other than that she has recuperated from the heart worm treatment and will go back in a few months to get a blood test to make sure there is no infection. Thanks for asking!
PS She has gained 4 pounds. I am trying to get her out walking and exercising a little at a time!
