I have a Eurasier..she was one last week, and we got her at 9 weeks of age, from a very lovely and very responsible breeder ..only had one litter from her bitch and is planning one more for next year from one of my girl's siblings (who went to her own daughter).. no puppy farming going on.
The good bits... they are wonderful dogs. Utterly devoted to their own family. Mine was toilet trained by 11 weeks, slept through the night from 10 weeks has never chewed anything up, she's daft and goofy and has a real sense of humour (never brings a ball back but runs up with it 'boops' me with it and runs off again. Her recall is pretty good , although a bit selective now in adolescence! She learned basic commands within a week.
She adores every member of the family but is timid with strangers until she knows them, barks very very rarely (but it's a HUGE woof when she does) and she loves to play with other dogs..has a 'best friend; cockerpoo who she adores.
We don;t have little children but she is always gentle and interested in ones we meet in the park and I suspect most Eurasiers would be very good with kids.
The not-so-good bits..
Eurasiers are family dogs. They don't like being left, and certainly not for hours on end. If you have a puppy you would HAVE to have puppy day care and not just someone popping in..and many places don't accept small puppies because they can't be walked for long.
They shed..a few times a year and then they do, it's EPIC. I could stuff a duvet cover with what I have raked off Orla this last month as she is blowing her winter coat..they are double coated and look awesome but you have to start grooming them early..mine tried to eat the brush at first but now she just lies there and enjoys it!
They can be picky with food..and they are clever.. they will hold out for cheese
(or that might be mine)
Whatever the breed standard says, they tend to have quite a high prey drive.. mine doesn't hassle OUR cat but a random cat in the street...or a squirrel, or a deer... if she's off lead she WILL chase.
They can be stubborn. Mine wont toilet in the garden and so has to go out late at night for a last wee... she puts on an oscar winning performance every night.. climbs on me, rolls around being extra cute and pretending she doesnt need a wee.... then goes as soon as we cross the road to the green by us 
She is our first dog.. and honestly I cannot tell you how much joy she has brought us, how many friends I have made, and just how much she enhances our lives. BUT she has also tied us down completely. I work 4 days a week, but my ds2 works afternoons, so hes with her most of the day and she is left for 1 1/2 hours on her own..and we worked up to that. She actually cries with happiness when I come in.. that's how much they NEED their family to be there.
I have no regrets getting a Eurasier (and I love how people comment on her..she is stunning and unusual)
PM me with any questions and also tips on who to avoid.. there are not many breeders but some are, shall we say, more notable , than others!
