Coco is a show cocker and she is certainly not a quiet dog - in fact she is a right gobby little madam
Anyone on here who has met her will confirm this.
All cockers are different but as a breed I don't think they would normally be described as quiet.
And as for energy, she would be on the go all day long given the chance - she really needs a good couple of hours of energetic exercise to be happy.
She is pretty good in the evenings though and will just snooze in her bed.
She can be quite stroppy though if she has not been kept busy enough and she will get into all sorts of mischief
- some people have a lazy dog but cockers are generally pretty high energy. After all that is what they are bred for, to be out in the field and working all day - working cockers are more energetic generally but show cockers are still more lively than the average dog IMHO
Sorry if this is not what you want to hear but you really do not want to live with a frustrated cocker
