Has she seen your dogs?
What are her qualifications?

I agree that 2 bitches can be kept together
bitches of the breeds you have can be kept with other breeds
yes keeping them seperate for a while for things to calm down and introducing them again slowly, calmly and positivly may help
None of us have seen your dogs and dont know your ability as a trainer either so we dont know what is possible
I hope things work out for you, the odds sound stacked against you but it is possible, but sounding unlikely

I am not sure about the advice to get your girls spayed, usualy people offer that advice for male dogs - and I dissagree with that - personally I would not neuter an animal to try and fix a behacioural problem as it can make things worse
and aggression is mentioned as a possible side effect to beutering and spaying in some cases
I dont really have much experience with that so hopefully others would have better advice

Best of luck with your situation, you are having a bit of a nightmare at the moment - I hope this is the bottom and things start getting better for you from now on

Could I ask who you saw and where are you in the country?

I am also in Ireland.

Anyone else feel that this thread is getting sillier by the day?

Dog groomer says it`s ok...

Yes! I am sure if the solution was that simple the many experienced people trying to help him would have suggested that on the first page

i agree

normally i hate such accusations on threads, but on this occassion im intrigued as to how one wouldnt doubt the veracity of this thread?

I aleady pointed out something earlier....but it was ignored
The first post says it's the other dog fighting

Are the schools on holiday in Ireland?

The mother and daughter I had were both spayed and it didn't make any difference. I wouldn't pin your hopes on it, but if they need to be rehomed in the future, spaying is a really good idea so they can't be bred from. Is your male neutered?
