I have a cockapoo and he is great fun. He is 10 months old, and weighs just over 11kg, so is quite a small dog (see profile).
Patch is an excellent family dog, and is very daft and playful. As a pup he did nip, and did the ambushing feet from behind the sofa trick. However, I think that many pups do this. He grew out of this with the help of chew toys and distraction, and does not bite even when excited.
His main fault is over friendliness. He does love people, and can expect cuddles from strangers. When off lead I do an eye out for families with young children or frail elderly people. He does still jump up a little, but good training can sort this out, but does not always get reinforced by my children or husband
. His other fault is that he steals things at home. Socks and shoes are a speciality, but yesterday he ate a fountain pen. His poo that afternoon was bright blue
but he was fine. His recall is excellent, and he does not like to wander far from me because he is a total wuss.
Any bad behaviour is usually due to lack of exercise. The pen incident happened when we were eating breakfast, so he was due a walk. I exercise him for 1-1.5 hours in the morning, and he has shorter walks in the afternoon. He adores his ball (spaniel) and can have separation anxiety (poodle?).
He is my first dog, so I have probably made loads of mistakes. However, Patch has lots of friends in the park, both human and canine, so I cannot be doing to badly. He is much more popular than me! I do not think that cockapoo's are harder than other dogs, but they are not easier either.
