I think you'd be a lovely childminder, in a lovely home in a great location. Go for it.
Don't be put off by the anti dog brigade, MNers are largely weird about dogs.
i would be totally fine with your dog & I wouldn't want you to change your family/dogs routine. I wouldn't want you to shut your dog out. The only thing I'd like to see is that your dog has somewhere to go away from the children if they wanted to.
school run wouldn't bother me, I'd prefer it if it was a walking one, rather than car, but it wouldn't put me off either way.
dog walks/shopping/Drs/dentist... for you or your kids would all be fine with me. I'd choose a childminder for the 'home from home' nature if it and unlike a prolific poster, I wouldn't actually need your full attention in my DC every second, they need to learn to share & take turns.
and actually your own (childminders) kids take second place for basic things & id just assume you'd prioritise down to 'need' not who birthed them!!
You won't be short of people wanting places!
best wishes! I personally couldn't be arsed with Ofsted & their nonsense, nor most of the parents! Love the kids though!!
oh and do you think you could train your dog to toilet in a specific area? It's not that difficult and you can buy an open pen type thing for the garden for them. Its nice to keep it in one area.
