Oscar (g.s.d x collie) who is normally quite good with our other dogs turned on Ollie (rottie x collie) and then went for Hazel (border collie)
Ollies is the most dominant and turned back and started a proper fight where as hazel backed down and went to hide
Oscar is 14 months old and not neutered Ollies 16months old and neutered hazel is 18months not neutered Oscar has been quite aggresive for about 3days nothing seems to be wrong with him medically and hazel isn't in season,
What can i do as i can't put them together as as soon as i do Oscar goes for one of them haven't got a clue what it all started over normally theres an odd growl but nothing major.
would it be best to re-home one if it continues if so which one as i want whats best for all of them.

Is hazel coming into season?

no she was in season about 2months ago

She's at the right time for a phantom pregnancy, then. Perhaps she smells unusually hormonal and this is what is causing the upset?

Hi Hannah sorry your tribe are not getting on. How long have you had Oscar now? Maybe he feels the time is right to challenge Ollie for the top spot and Ollie wanted both back in Line?

he's 14months old and we have had him since he was 8wks old
normally oscar submits to ollie and shows his underneath and will lick his mouth
we tried putting them together earlier wothout any others around and both were snarling at each other so ones in the kitchen/hall and one in the lounge tonight ones they are both going to stay seperate from all other dogs

Hi, how was your night?

I too am having trouble with my girls at the moment, both are bulldogs, Hilda is almost three, Gladis has just turned one. The problem I am having is Hilda can be very nice and loving towards Gladis at times. It usually happens when we are fussing the pair, they both get very excited and want all the fuss for themselves, but I do try and share it out, so I will be fussing them both at the same time, then all of a sudden Hilda will just turn on Gladis and snap at her. If we pop out we now cannot leave them in the same room together as we could before as we are coming back and finding Hilda has nipped her, so they now have to be seperated. The thing is Hilda will then go up and lick Gladis and clean her, so I really can-t understand what is wrong. Hilda is spayed, Gladis isn-t and is now starting to stand her ground with Hilda. What can I do?

Jolene

they were kept seperate last night let them out this morning Oscar grabbed Hazels neck and then when Ollie came to see why she was squeeling Oscar started on him not as bad as before but both were snarling and snapping. Ollie is fine with hazel so Oscars in the dog crate at the moment going to a dog show 2morra so there going to have to be on best behaviour

Your younger bitch is now entering adulthood, and as such is becoming a rival.... Try to fuss one dog at a time, rather than sharing fuss out 'fairly' - dogs don't see it as being 'fair' they see it as one getting a larger dose than they should have - and this is what leads to the fights :( Human attention is obviously very important to Hilda, but as a spayed dog, she occupies a lower status than Gladis which is why she licks her (especially around the mouth I'd guess?). Different dogs value different resources, some food guard, some toys, others their humans. These resources often have no connection to the dogs status within the pack, it's just something the dog feels sufficiently strongly about to face up to a superior....
