Sprocker, like springers and cockers are great dogs.
I have 2 working cockers. I also Foster soaniels and have had lots of sprockers through my house.
With sprockers, they can come in a range of size. We have had huge ones and small ones.
Whilst they are great, they do need alot of work. They are excitable and (generally) intelligent. You can exercise them all day, but if you don't stimulate their brain then they become difficult.
The rescue I work with, think they get so many in because of the current popularity or cross breeds. Often sprockets are a mix of show cocker and springer. The thinking being that as show cockers are generally considered calmer, it will calm the srpinger side. They are rising in popularity. And often by people who are unprepared. Though this happens with all breeds.
It usually doesn't. I have also had show cockers in the past. One of my working cockers is really lazy. More lazy than any of my show type, ones. Theres general breed traits. But not all dogs conform.
The ones I foster are usually between 7 and 18 months. When people realise they just cant cope. They are big, bouncy and often untrained when they arrive.
The majority tend to shed like nobodies business.
But, if looked after well. Physically and mentally stimulated, they are wonderful.
Recall is often easy to teach them. Its keeping up to it that can be hard. We manage it by keeping them focused on us during walks. Letting them wander and run, but keep calling back for treats. Playing games with the kids. On walks the kids would often hide and then the dogs have to find them. We start this game in the house.
Also, when it comes to picking a breeder, flow all the usual guidelines. Sprockers were often farm dogs. They arent a pedigree (even though cockers and springers come from the same line) and it may be more difficult to find breeders that health test both parents.
