My husband was ill last night with a slight fever and nausea. TOday my Doxie is lethargic and not eating. Is it possible that she could have caught my husband's illness?

Not likely, probably a coincidence. If your Doxie is still lethargic and not eating in the morning, suggest you see your vet ASAP.

thanks for your reply. Dog in hospital getting hydrated -vet thinks pancreatitis but is doing extensive blood workup.

I am so sorry to hear about your dog. Pancreatitis is very serious. Sending positive thoughts that she will be okay. Keep me posted.

Is it possible your dog transmitted a zoonotic disease to your husband? Zoonotic diseases are those transmitable to humans from animals ie ringworm, rabies, chlamydia, hookworms, salmonella, septicemia, I could go on and on. Don't let me freak you out.

It is unlikely your husband caught you dog's illness; it is unlikely your dog caught your husband's illness. Just chill. Everything will be okay.
