It's their home too.
OP's situation was a rescue dog from a likely abusive previous home. There are often pets available for people who are not able to handle that situation; My dog peed on the rug occasionally for about 3 weeks, and pooped indoors twice, and it's not happened again in 3 years. To pull the "children" card, children make huge messes, cannot be unattended or unsupervised for years, destroy homes, and yet that's not seen as "burdensome"
