Thank you for the support and validation. I have other issues in my life that have me depressed and anxious (add to that a family tendency), so I can't say it's just my dog. My husband is very supportive. It's nice to know that there are so many who feel the same way.
The trip to the vet was good. I told him everything we've been going through and he recommended going back to a homemade fish and sweet potato diet, a multivitamin, duck or venison treats (I got duck jerky.) and Revolution for flea control. I also showed him the homeopathic remedy and he was ok with that and the 1/4 tab of cortalone every other day. All that for $22.
I took back the dog food, got the multivitamin, duck jerky and went to Winco and got some salmon and sweet potatoes.
Came home and Latte loved the jerky and just ate a plateful of tilapia, salmon and sweet potato. She's happily snoozing on my lap so I will get back to my knitting.
I sincerely appreciate all the helpful comments!
