We are going to see a litter of working cocker pups tomorrow. We have a one year old Springer already.
We found the breeder on champdogs, this is the only place he advertised as he only had a couple of pups available, keeping one himself and four going to working homes, pre booked before the mating.
I was interrogated basically as demand for his pups has been high and he could chose to a certain extent who he felt suitable, which I see as a good thing, and we must all go as a family. Personally, I would be wary of pre loved etc. ensure health checks are done and ask to see paperwork etc. expect to be interviewed yourself!
We chose working cocker as a breed to compliment our Springer, good natured, happy, good with kids, intelligent, super temperament, but too big etc.We keep our dogs fur pretty short so I don't notice the shedding to much tbh.
Our Springer does get at least 2 hours exercise a day, probably more like 2.5 and we train him too, but the kids are older and I don't work that many hours, so I find it easy tbh. Walk in the morning when I sort the pony anyway then a really decent one too in the afternoon. In the summer, the kids or DH walk in the evenings as it's light still so the walking is shared more.
Our Springer will take any amount of exercise we through at him, but in the house is very chilled and relaxed, so I am thinking a cocker would be similar.
I think if you are prepared to put the work in, you'll be fine!!
