Back from the vets with lots to think about. Vet examined and found no physical reason, until he took his temperature and it was 104. So... the vets advice is antib's, then maybe take bloods later. I asked (as for me getting started on a solution both physical and mental promptly is what i need) to get bloods done today. So i get results back of bloods tomorrow and he's taking antibs for the next week.
The vets opinion is that he was 'probably very grumpy due to feeling ill, like we would be if we had flu' and thinks that as he's not usually a growly/aggressive dog/with issues, once he's feeling better he's probably ok, and if not to go down the behavourist route then, but to obviously keep Emily and Fred apart from each other until then (er - yeah, thought that would go without saying!).
Can i just say in Freds defence (maybe misguided, who knows) that neither attacks can be classed as unprovoked. Although Emily did not provoke him per se, in his eyes like Mark said, resource guarding the chair, and then me could class as a trigger.
I however, feel that although the temperature may be a cause of it, i also think the resource guarding may be an issue and will be asking for recommendations for a trainer - if anyone can point me in the right direction?? Maybe Fred does resource guard (as he has with food in the past) and that feeling ill 'tipped him over the edge' into reacting, whereas normally he wouldn't...so maybe usually he does have a problem but deals with it when he's feeling ok, so maybe an underlying issue that still needs to be addressed IYSWIM)?
I feel a bit better now, a little chink of light. I WILL definately persevere and try whatever i can. Fred is already castrated, and insured (need to check to see if it covers behaviour - if not, then I'd throw whatever money is needed into it, as Fred is my family and deserves all the help we can get him.)
Thanks for your replies. I guess Emily being young makes it harder to manage. I grew up with aggressive (through fear) rescue dogs from the age of 8, but at least at that age you can be educated in what to do/not to do around a dog.
Thanks for all your replies. They are appreciated a LOT.
