I feared poison as well when I first took her in actually. I don’t believe they had enough time to do any type of official tests on her (or that’s what I was told anyway) so there is a possibility of it not being DCM. It’s hard not having concrete answers. I keep wondering if maybe she got some kind of infection that worsened what might have already been there.I'm so sorry for your loss, it's just so much worse when they're just a baby.
It sounds like you have a competent vet, which is amazing, I've had two Dobes die of undiagnosed congestive heart failure. The second one, I caught-on to the symptoms and diagnosed him while the vet (an associate in the practice who was not my usual vet) was chasing what he thought was a mysterious infection that produced no elevated body temperature, no positive cultures, and no response to any antibiotics, even with the more unusual tests and drugs. I'm not happy about the wasted time, money, and trips to the vet on a wild goose chase of a misdiagnosis.
Anyway, there is nothing you could have realistically done if such a young pup was suffering from CHF. I'm guessing the vet did some differential diagnoses to go with deciding it was probably CHF rather than poisoning. I would've leaned towards poisoning from the medical history/onset of symptoms you provided, but only because she was so young. I'm guessing they did liver/kidney/blood screening, and found no evidence of acute toxicity.
The symptoms fit CHF. There will usually be elevated breathing rate, sometimes labored, sometimes coughing due to fluid accumulation backed-up into the lungs. There will be poor perfusion of oxygen to the body. There will be lethargy due to the poor perfusion. Seems to be a good diagnosis from what you describe, just really tragic.

Maybe if I’d taken her in a little sooner something could have been done. Maybe she would still be here. My two youngest are struggling with her loss. She was our first and only family pet.
The vet we have does seem competent though which is fortunate.
I’m so sorry at your bad experience with your vet and at the loss of your two dobes. May they both run free and happy
And there's no problem with that since we all have to take it at our own pace.For now though, we are trying to heal. Our hearts just can’t add another pup to love yet.
