Hello, I am Dr. Peter a licensed Veterinarian. I would like to help. I need to ask you a few questions to be well informed and give you the best advise. There is no additional charge for information request.
1- Is she spayed?
2- Any pre existing medical conditions?
3- Can you take a rectal temperature?
4- Take a look at her gums and see if they are pink like yours or pale?
She is spayed,
she takes thyroxine .7mg twice a day for a thyroid condition
I do not have a thermometer
Her gums are pink, not pale
The symptoms your dog is exhibiting are very non specific to even isolate what organ system may be the problem. This case needs a hands on exam by a veterinarian. I understand your local vet is closed. But, maybe there is an ER clinic not far from where you live. Consider having her checked by an ER vet.
I have submitted this as info request so you do not get charged. I am sorry I could not be of more assistance in this case.
Eating is always a good sign.
