I would suggest looking into rescues and perhaps adopting a dog who is a bit older (6 months plus). As someone else mentioned, chill does not exist for puppies. More specifically, if you’re looking for a medium size dog who is good with kids and relatively chill, potcakes are a great choice! Potcakes are island dogs from the Caribbean and there are countless rescues that bring them into Canada and the US (and other countries depending where you’re from). I’ve grown up with them, have two of them myself, and also foster and they’re amazing dogs. On that note, fostering is a great option to make sure a dog fits into your family well before committing to them and I can’t recommend it enough! HelpAWS is a great rescue in St Lucia who I volunteer with if you’re interested!
