........ would you mind telling everyone more about your experiences please ?
I'd be particularly interested to hear from people who have siblings that are above 2 yrs old - rather than those who have pups - as pups are very likely to still get along well - whereas dogs past their "teenage" phase might not....
I'd like to hear if they are 2 males, 2 females, or one of each.... And how you got along training two dogs, did you take them to classes together, or separately ? do you walk them together or separately - and do they get on well with other dogs, or do they gang up on other dogs, and / or defend each other..... do they listen to you, or do they ignore you and play with each other ? do they ever fight ? did you have both neutered , or only one, or neither - and what were your reasons for that ? do you have other dogs in the household as well, or just "the siblings" ?
My own personal experience was when I still lived at home many years ago
- my mum has always had Cavs - she already had two bitches, and then she got two more bitch puppies, litter mates. They were the best of friends forever, til they died aged 12 within a few months of each other. She never had one problem with them - with each other, with the other dogs, or with anyone elses dogs - although they didn't really want to interact with "strange" dogs, preferring to keep themselves to themselves. She never took them training, and yet they were incredibly well behaved and obedient. However - as I am sure you all know Cavs are a totally different kettle of fish to Cockers, so I wouldn't expect the same situation to necessarily apply to people with cocker siblings.
I hope you don't mind me asking these questions - it is a very interesting subject and more and more people seem to be getting two puppies at the same time.
