Really Want A Dog But My Parents Wont Let Me?

I have been wanting a dog for several months now. I have had 2 dogs in the past but my dad got rid of them. One of them had brain damage and the other we couldnt potty train. But that was about 2 years ago. They were our first dogs so we had no idea how to potty train them so… bye bye! But i have been on Petfinder.com and have watched all the dog traing and care videos. i watched them all so much, i practically memorized them! i really want a small dog like a bichon friese or cockapoo. sumthing like that. i have good grades and am very responsible. i have a 3 year old tiger cat who i feed, excersise, and clean the litter box for. ive had him for 2 1\2 years. i have researched dogs and breeds and i know im ready? but how do i persuade my mom and dad? ive tried EVERYTHING!!!

What Would The Puppies Of Two Cockapoo Parents Turn Out Like?

I saw this as question open for voting on, but not answering. That’s because all the answers were wrong!
An F1 Cockapoo is a cross between a Poodle and a Cocker Spaniel. The resulting personality is unparalleled in its ability to relate to people and children. They are famous for being loyal, affectionate, open and friendly, eager to please, easily trained and they don’t shed.
Purebreds and inbreeds often carry genetic disease. Heterosis is the phenomenon where crossing two inbred lines can produce descendants with superior genetic foundation. This goal in this scenario is not to create a new breed, but to create a happy and healthy pet. You lose this benefit when you inbreed cockapoos(F2).
So the question is not what would they look like, but would they be healthy? Do you have an F2? Is it healthy?
In my opinion, If you get a cockapoo, get an F1 Poodle-Spaniel mix. Go to a reputable breeder, choose your pup based on personality, looks etc.
Am I right?
