Hi, not to alarm you but I am having a similar problem with my 2 Cockers who are now 18 months old. I have a 3 year old Springer who was a piece of cake to train, however my Cockers have been a nightmare - the only time they are good is when I crate them but I don't really want to have to do this all the time. Sometimes I can leave them all day and they can be really good but other times I only have to pop out for 15 mins and I will come back to a mess.
