Op - a "bordoodle" is one of the most irresponsible crosses i can think of.
Both are high energy, high intelligence dogs. As collies are still bread to be working dogs, they can be obsessive and difficult to manage without a huge amount of stimulation and exercise.
Both have lovely temperaments, poodles generally have a slightly gentler nature. Be aware that there are small variations in temperament between standard/miniature/toy poodles. They are though very clever and can be stubborn but do make lovely family dogs.
They both require a lot of attention and exercise.
The risk with this cross breed is that you get a puppy with the difficult traits of both dogs, which would be an absolute nightmare.
Not to mention that since the pandemic, irresponsible breeding has rocketed and vets are reporting a huge number of dogs bred very badly in the last 18 months with significant physical and behavioural issues as a direct result from the breeding.
Another point to be aware of,the demand for poodles and poodle crosses has rocketed in the last couple of years. Not only has this contributed to unethical breeding but it also means their a prime target for dog thefts, which have also rocketed recently. So, any poodle cross is likely to be a target atm.
As you are a first time dog owner, I would urge caution and plenty of research before you took on either a border collie or a poodle. I would strongly advise anyone against encouraging this cross breeding, irrespective of their experience of dogs.
If you are set on a poodle cross, opt for a more usual one such as a labradoodle or cockapoo.
I must ask, and I mean it in the nicest way, when you say you're looking for an usual breed, why? Is this because you see your breed choice as a reflection of part of your self/personality?
Its normal to do so, but it's a very bad idea to make this a driving reason for your dog choice.
Prioritise your wish list for a dog: if one that is hypoallergenic or doesn't shed is high on your list, then opt for a pedigree that doesn't shed rather than a cross between one who sheds and one who doesn't.
Be realistic about how much time you have for walking, training and spending time with your dog. About how much time its likely to be alone for. Be realistic about how much this might change post-pandemic. Also be honest with how much you're willing to be compromise for a dog, because no dog simply fits into your existing lifestyle.
Speak to local animal carers - vets, shelters and behavioural experts as part of your research and be aware that if you choose an unusual breed or a breed that is predisposed to health or behavioural issues you could be taking on a very expensive pooch.
This is all before you do thorough research into the breeder that you look to adopt from.
A final comment: cross breeds are now costing at least as much as pedigrees, so you really want to sink potentially thousands of pounds just to buy (not factoring in the costs of upkeep, training, health etc) into a cross-breed that has been bred irresponsibly and unethically and which comes without the assurances of breed that a pedigree is likely to come with?
