If you are first time owners and don't have someone home all day then don't get a puppy. It is honestly like saying you want to have a baby but can't take any maternity leave.
My honest advice to you is get an adult dog from a rescue. Even if you have to wait. You have no guarantee of temperament with puppies. My 2 are the same breed and couldn't be more different.
At least with an adult rescue you know what you are getting. There are plenty of them is rescue centres who have no behaviour problems and their history is known, its just a matter of putting your name down and waiting for your perfect match.
Puppies are like toddlers who don't speak English, don't wear nappies and take a minimum of 2 years to grow up enough to be reasoned with. And breed doesn't guarantee anything. My two are the same breed but polar opposites.
Housebreaking them is a nightmare. Especially with smaller breeds as they can only hold it an hour or so. You can't leave them alone for more than an hour and have to get up every couple hours through the night to let them out to pee or clean up the mess if they didn't make it. If you use puppy pads they don't always distinguish between the pad and the dropped jumper/cushion/rug etc.
Also say goodbye to days out unless you have someone to look after them.
They chew. Everything and everyone. Ddog1 is solely responsible for no less than 2 dining tables, 1 fire surround, 6 doorframes and a dressing table. And countless items left lying around, phones/ipod/ remotes etc
She is the sweetest most well behaved dog as an adult, I get compliments on her all the time but the puppy years were brutal. Training is hard. You can't just think fuck it I cba today because if you give an inch they'll take a mile and you're back to square one. You don't know if they'll have behaviour problems until they hit adolescence.
Ddog2 is goofy and biddable but thick as 2 short planks. He took forever to train and his recall is still shaky plus he is reactive so walks are like a military operation with Ddog1 acting as scout. She runs ahead and if her ears go up I wind Ddog2s lead round my arms and brace. There is no reason for this. I've had him since 8 weeks, he has never had a bad experience. No trauma, no abuse, no fear, he's just a dick.
I honestly adore them and don't regret them for a second but the puppy years nearly broke me. I wouldn't do it again now I'm working full time. I just don't have the patience of my 20 something year old self.
