Thanks for the additional information. It is helpful.
What it sounds like to me is the possible start of pyometra which can be deadly. Pyometra generally occurs 60-70 days after a heat cycle. It is usually seen in older unspayed females but can be seen in any age. It is diagnosed by ultrasound showing fluid in the uterus. There are two types of Pyometra (open and closed cervix) Symptoms of open cervix Pyometra are a vaginal discharge that may be pus or bloody, lethargy, anorexia, increased thirst and urination, vomiting and diarrhea, and abdominal swelling though the dog remains fairly healthy due to the infection draining from the body. Closed cervix Pyometra symptoms are the same without much of a discharge, they appear very ill, there is usually weight loss and abdominal swelling and is much more extreme. Dehydration, shock and death can occur if not treated aggressively.
I'm guessing it might be early in a case of closed pyometra. Unfortunately, imaging would likely be needed to diagnose this. Treatment for pyometra is usually an emergency spay operation. Another possibility might be diabetes. Dogs with diabetes tend to not be able to gain weight even though they are hungry all the time.
She might be vocalizing trying to let her owners know she is ill. That part would be more difficult to determine the cause of since many dogs bark excessively even when well.
Since the dog obviously needs to be seen, the following sites may be able to help.

This site may have additional resources as well.
These vets may offer a free initial visit though you may have to pay for extra procedures and medications. See the next one for the coupons.
Now some vets will treat a dog and set up payment plans. Others will agree to treat a dog if the owner will sign the dog over to them. They lose their dog but the dog is able to receive treatment. Humane societies work differently in different areas as so rescues. Some will treat a dog even if there is little chance the animal will survive while others will let a vet make the decision on whether the dog has a good chance of surviving before allocating funds for the dog.
I wished I could tell you for sure what the problem is with her, but testing will be needed to determine the exact cause. Now a dap collar may help calm her a little. They are available at pet stores. Benadryl often has a sedative like effect on some dogs but in others, it can cause a hyperactive state. Benadryl is dosed at 1-2mg per pound every 8 hours. I do really have to advise she be seen so perhaps one of the vets on the fee first visit list will be able to see her quickly.
