Most shelters will take them back if they have issues you can't deal with. Which is more than you can say for most breeders. And many dogs are over-bred and have more issues than a mutt in a shelter will ever have.
Any reliable, responsible breeder will insist that if there is any reason you cannot, or don't want to keep the dog that you must return it to them. It is the backyard breeders, whether mutts or purebreds that cause the overpopulation of unwanted dogs. A reliable breeder questions prospective owners to ensure their acceptability for owning one of their dogs. Though not foolproof, it is good to know they care.
The issue of having deficiencies bred in to purebreds though is a huge issue. Again, if one goes with a good reputable breeder, this is not as likely to happen. It is usually caused by the backyard breeders trying to make a quick buck on a popular breed. I have to sign in our contract to purchase an Aussie that we will either neuter the dog, or return it to the breeder (We would have done this anyway). They are very selective which ones that can be used for breeding. I assure you, with the breeders I know, this is not done to corner the market as some believe, these breeders really do care about their dogs, to many they are part of an extended family.
I love mutts, the majority of dogs in my life have been mutts. As I mentioned before, one of the reasons I am going with a purebred is to ensure the size of the dog. I know my brother got a mutt from a Border Collie mother thinking it would be medium sized, and ended up with a full grown Black Lab outta the deal. 
The cost of a purebred is not that big either, 1/4 what I just paid the dentist for a new bridge in my mouth.

We have a dog door big enough for Cara. And yes, the little nieces and nephews crawl through it all the time, lol.
As far as 'letting people into the house' goes... if you saw a dog door that big, would you be brave enough to go into the house?

One would want to be cautious.
