You certainly need to sort your work days, but hopefully you've grasped that. Far too long to leave a dog without attention and outdoor access.
If you think you will struggle to afford the vital dog walker, you certainly can't afford a poodle cross, or anything else that will require similar regular professional grooming, so don't forget that. (Let alone the ridiculous prices charged for the puppies in the first place ...) It is staggering how every post enquiring about dog breeds seems to think they're one of the best options LOL.
In addition, the poodle crosses I know, whilst being charming little dogs, do NOT tolerate being left much at all. My neighbours' one in particular cries pitifully on the days they leave it, from start to finish, poor love.
Yes, I have tackled them about it.
Again, if money is an issue, please do not overlook the importance of doing your homework and buying right, ensuring that you look at breed club websites for all recommended health tests. Obviously, if you are buying a crossbreed, you need to ensure that both parents have the recommended tests for their breeds, crossbreeding does not magically negate this whatever breeders tell you. A cheap puppy can be a very false economy in vet's bills.
Whatever puppy you get, you also need to be able to afford a good insurance policy too, all the more important if you need to watch the pennies. The healthiest dog in the world can have accidents that cost £000s.
Oh, and it goes without saying to make yourself aware of the evil puppy farming trade. If you do not take all possible steps to avoid it, you are supporting it.
