I love animals very much - I have my dog here on my signature and we just adopted 2 cats a month ago. Does your dad live with you? If you're taking care of this dog, I don't think it's safe to keep him, when you have an 18 month child. If you had a bigger place, with a large enough yard - then it would be alright and you could eventually train the dog. But in a confined space it would be a battle. If your husands not crazy about dogs and your son is too young to assert himself - it's better not to have the dog. Trust your instincts
