Controlling risk of infection on treatment

It's not really a bacterial infection from dogs you need to worry about its the viral ones which can get to pneumonia quickly.
I did shave the whiskers off my Schnauzers so I didn't have to worry about dirty beards but they still stayed inside the house.
Visitors had to suck on an antibacterial Strepsils lozenge and if I went out in particular for that first blood test after the first chemo, I sucked a lozenge and wore a face mask. That proved a good move as my disease resistance in the blood test came out at zero. Not 2% or 4% but zero. Thereafter I was given an injection to help out after each round of chemo.

I lived as normal with kids and a cat during chemo.  A bit more attention to hygiene when out - if I had to use public loos, I had disinfectant wipes in my bag...that sort of thing.

The thermometers we had from when the kids were small were not particularly accurate anymore so we bought a good ear thermometer online so that I could easily track my temperature.

Hi Penny. I live with two dogs and four children, had chemo and didn't get sick once. I don't think you have to worry about the animals. As @Afraser says, usual precautions should be sufficient. Don't let them lick you if you've got an open wound, scratch or somesuch.

I was careful with handwashing, keeping my hands away from my face, especially after being out and about. Friends who were sick weren't allowed in the house! But the pets were fine. K xox

It’s lovely that your husband is concerned! Many people have had little or no infection during treatment, so just take normal precautions. Main thing is usually high temperatures, treat them seriously and get treatment. It’s often sensible to keep at a distance, if possible, from people you know have easily transmitted ailments such as flu or even bad colds, but to be honest I didn’t find I got things any more easily. I had animals (dog and cats), all in the house - again, normal precautions, washing hands, etc. I got a couple of infections but they were caused by a persistent seroma and the germs that caused them were internal and were all my own!! Best wishes.
