Hi Mebesa, I am glad that you joined our forum...and very glad that you are asking these important questions.
I considered sending you a private message, but decided that what I have to say is important for all people considering a Labradoodle.
You seem to have some serious issues that you must consider (your health and ability to exercise the pup, the fact that it will be crated for long periods on a regular basis, and now your uncertainty regarding the personality and temperament of doodles...all of which are EXCELLENT concerns and I do not wish to make light of them.)
It would be easy for me to lightheartedly tell you that you are concerned for no reason, that doodles are great, friendly, loving dogs...which they are GENERALLY. But the reality is that not all of them are. Some are not bred by quality breeders and you may well get a puppy with issues.
Most doodles train extremely quickly, but that requires a lot of time and dedication on the part of the owner.
If you are crating your puppy for 5 or more hours per day, you are not able to physically exercise with a puppy or if you are unable to spend the necessary time to train the pup, you are wise to question whether or not a doodle (or other dog) is right for you.
Dogs don't come hardwired as perfect companions. It takes a lot of work and patience...and with doodles, it takes a lot of attention and love.
If you do not have these things to give, then it is probable that you WOULD have problems with your puppy.
We absolutely adore our dogs...but we have had them eat furniture, shoes, plants, insullation, cell phones, etc. Why? Because we are not as good with the training as we should be!
We have barking dogs too, but it is not the dog's fault...it is ours. So, I am speaking from experience, and with a sincere attitude of helpfulness (not blind support) in telling you that, given your questions, I would suggest that you continue to research...that you, perhaps, offer to dog sit a puppy for a couple of weeks and see what happens.
I really do hope that your selection will fit into your lives because our dogs have brought us nothing but joy and happiness...but that has not come without a price. I guess I am asking you to consider the price...it is far better to NOT buy a puppy than to find out later (after the dog has fallen in love with you and your family) that you don't want to be a dog owner any longer.
(Please note that there are many good and loving people who have had to rehome doodles and I am not judging them...I am simply asking you to consider all things, including what is right for your pupppy.)
I wish you the best...I really do!
