Hello, welcome to the forum! Lots of passionate parrot lovers here, and lots of great information.
People do have parrots and dogs or to me even scarier parrots and cats. Both species have killed parrots here in the forum, we hear about it a few times a year.
I have small dogs that grew up with parrots, I never trust them or allow interactions, and work on training. But it is a risk. Parrots are curious, and dogs prey or play instincts can be triggered, continuously diligent.
GGC are cute clown babies that will steal your heart for sure! When they mature they are still cute clown babies, and snuggle, but use that beak to keep you in line. So have a reputation fir being nippy. If you learn to read them and, give them a moment to collect themselves and realize that hand isn't going to kill them you can avoid this.. mine is a love totally, but quick mood changes could lead to nips weekly. But are avoided as I read her. 10 seconds and she us back to sweet.
Other household dangers exist, like toxic fumes from Teflon and the same chemicals in other nonstick, insts pots, air fryers and more, I use cast iron, glass and stainless steel to cook with. As no room in the house or even a different floor would keep them from death from the off gasses. Burnt plastic, new paint all deadly. Putting vinegar in coffee pot or dishwasher off gasses deadly. Cleaning with vinegar in cold water a ok.
Fresh veggies and leafy greens should br part of the diet , fruits more rarely a few times a week and pellets, seedmix. Some do pellets and the fresh stuff, but still 10% seed mix is a good idea.
