Cancer or pyometra?

My lab who was quite healthy up and until August started to show a dulling coat and pot belly. I assumed parasites. I took to to a vet for worming which they did, and they also told me they noticed a tight abdominal area, as well as some muscle wasting. The question was raised about possible Cushings disease, but the vet did not pursue it. After the de-worming, I took the dog back in within one week as she seemed to be growing in her discomfort levels. Xrays and a geriatric blood panel were taken.
The blood work showed elevated WBC of 18 (reference range was 4.0 to 15.0); low RBC 3.9 (reference range 5.5-8.0); low hemoglobin 89 (reference range 138-199); low meatocrit .30 (reference range .39-.56); high mean corp volume 77.3 (reference range 63.0 - 77.0); low MCHC 296 (reference range 326 -374); high RDW 19.9 (reference range 10.0 - 19.0); high neutrophils 15.480 (reference range 2.800 - 10.560); low urea 2.2 (ref. range 2.5 - 9.6); high total protein 79 (ref. range 51-78); low albumin 24 (ref. range 25 -36); high globulin 55 (ref.range 20 - 40 g/L); low albumin/globulin 0.4 (ref. Range 0.8 - 2.3); high amylase 1249 (ref. range 328 - 905 IU/L). Hematology comments read "review of glass slides reveals a mild anemia that is non or pre regenerative reticulocytes are borderline. Leukocytosis- suppurative inflammation; anemia could be anemia of chronic disease. Endocrinology came back within normal limits. Urinalysis states monitor crystalluria consider culture"

X rays showed a large mass in the abdomen. The vet simply said the diagnosis is consistent with a cancer diagnosis, take the dog home and let her die in comfort.

I was not comfortable with the Vet's flippant attitude. The dog came home and a week later came into heat. Her heat cycles which are normally silent heats were very different from this one. I put her on a high antioxidant drink (pure acai berry juice which the dog loves) her heat cycle this time included a heavy amount of dripping and sometimes it was a bit of a goopy discharge. I simply assumed she was cleansing toxins from her system due to the antioxidant juice. (It's known to detox a system.) Now I am learning about something called Pyometra and am wondering if this is a possibility to pursue. The xrays of which I have copies, are similar to the canine pyometra xrays I find online.

Her heat cycle has now ended having run the usual number of days. She showed no normal signs of wanting to find a male to mate with when out for walks.

The dog is comfortable; has loss some muscle mass; pants on occasion but not often; has a dry nose; is lethargic; and the last couple of days is showing signs of being weaker in the hind end; she is drinking normally, but I am also giving her juice 70 ml 3x a day by a syringe orally which she readily drinks and looks for more.

Based on all this info. Should I be worried about pyometra or am I simply wishing for a more treatable condition than cancer?

Should I be taking her lab tests and x rays to another vet for another opinion?

I would appreciate your feedback.

Thank you for your response.

To clarify the consistency of the discharge during Luna's heat or what I thought was a heat cycle (she was due for one) the discharge was not pussy in colour, and did not have a noticeable odour. At times it was normal like a typcial dog in heat and at times it was thick like tomato soup right out of the can--not watered down. I would use a cloth to clean up her hind end as she could not reach it due to her bloated condition. When I'd try to clean her up the discharge would almost be stringy like clinging between her and the cloth--very abnormal for a typical heat cycle discharge. Also, I have noticed that when people pat her heavy high up on her side just forward of the hip area she sometimes slightly yelps as if the area is tender.

By the way, the discharge ended this past week.

Her tests were done a month ago and the vet told me she thought the dog would be dead in two months. This dog doesn't look like she is ready to die.

Not sure if this information adds to your position or not.
