I know MN generally isn’t a fan of cross-breed dogs, but risking asking anyway 
MIL is allergic to dogs, which is why we are considering a cockapoo (and I know there’s no guarantee MIL won’t be allergic to a cockapoo, but think it might be worth a try as - anecdotally - I’ve heard lots of stories where people with allergies have been fine with this cross-breed. MIL says she has a neighbour with one and thinks she’s ok with her neighbour’s dog).
I grew up with cocker spaniels. We had - all of the time I was growing up - two at once. I love the breed.
I know cockapoos can inherit their poodle-parent’s intelligence and energy, but I’m not sure whether to go for one or the other or how they tend to differ apart from that.
(I would rescue a dog, but we have very young children (youngest is a toddler) and rescue places have advised me to get a puppy as even rescue puppies can be unpredictable because of their (often) sad backstories.)
Anyway - would you choose a cocker spaniel or a cockapoo for a family dog?
