Hi Charlotte, I’m also in the UK …we answer questions on here from a lot of countries.
This episode with Walter needs Veterinary attention. We cannot diagnose on here but this could be anything from a seizure to a mini stroke to something lacking in his blood/diet…..and needs professional assessment to find out what is going on.
I hope Walter is ok and try to keep him calm and quiet until you can get him to a Vet later today hopefully. Good luck.
Sad to say, this if a common occurrence when you adopt two males from the same litter. Either they grow up to be totally dependent on each other and can never be separated, OR they are in constant contention. How old are they? Have they been neutered? If they are over 6 months old they need to be neutered. This will help reduce the aggression.
However, it is not the cure. You need to find a behaviorist NOW! Don’t just pick any dog trainer – look for one that can come to your home and work with you there. Or one that specializes in aggression cases such as this. And sad to say – the only answer may be that you have to find one of the boys a new home. They may have developed such a dislike of each other that they will never live comfortably together.
You do desperately need help! But it is far beyond the scope of this forum. You need hands on help from a professional that can see your dogs and figure out what triggers the aggression. And in the future – remember – never get 2 puppies at one time!
They are almost a year old and have appointments scheduled to get fixed. You response is very insightful, but I do have one issue. One of them is a female. Does this make any difference? Thanks.
littermate syndrome – the issue you’re experiencing – has nothing to do with sex. it has to do with raising two puppies of the same age together and not giving them time apart for training and socializing.
and i agree with PK, this NEEDS to be handled at home. anyone giving you further advice online is being reckless. you need someone in your home, watching your dogs interact. until this can happen, continue crating each dog separately and rotating which has freedom in the house. this will help you to keep them safe from each other. every fight will get worse, every interaction will escalate, and you may end up with a dead dog if you continue to allow them to be around each other.
