Thank you again, Taryn, for your well wishes and information. I was going to research vets last night but I have been so upset by all I've read already I'm afraid by the time I finally fell asleep from exhaustion it was forgotten. I've hardly slept in the last month for worry, not that I haven't already got sleeping problems.

It was so nice of you to find those links for me.

Jenna got her second dose of keto last night and this is actually the first time in awhile that she hasn't gotten me up about three times a night to beg for kibbles or get a drink of water.
NP vet is actually closer to us than the one I currently frequent. I haven't been to them for about 12 years when a beloved cat contracted vaccine related sarcoma. The vet at that time could not give me a good prognosis so I looked elsewhere for assistance and never really went back. Not that he wasn't correct in his opinion but it devastated me. They did direct me to my current vet's practice for my exotics needs. I don't doubt they may be able to help Jenna so I will at least give them a call. They may actually have some record of my pup ironically, since the rescue I got her from is near there ( though I think the rescue organizer used the holistic vet there for the pets in her facility also.)
I was looking for images of dogs with Cushings and hypothyroid last night and was distressed to find one that indicated a similarity to what is happening to some of the folds in Jenna's belly skin above her hocks and in her armpits. It's called cutaneous atrophy and the image is on wikimedia. The picture is far advanced into the condition...Jenna is nowhere near that bad...but you can see some of the wrinkling forming. I can't find the condition related to anything but Cushings.
I hope that although these symptoms she has seem to have come on so suddenly, and she's young yet...supposedly only 3 1/2 years old...perhaps we have caught it early and can reverse any damage. I showed the picture to my husband and basically told him we need to prepare to have her tested. I'm sure he thinks I'm crazy but I can't care about that now. I just want Jenna's life saved. Since he has to do all the driving (in subzero cold and snow and with a questionable vehicle) I can understand his exasperation to a point, but right now all I can see are Jenna's big brown eyes in her tiny face looking to me for help. Something is not right and we have to find out what.
Sorry to just run on about this but I have nowhere else to go to take my worries and I've prayed myself to exhaustion for weeks already. Thank you all for being here. I don't know what I'd do without a resource like this.
God bless.
