Ok so here's the text my friend sent me exactly as she's wrote it

"Came back from vet he was v good not biased.he listened. said three options.bring him in for blood tests where can collect data tomoz mornin and if he somethin shows up he will pts. If not check out everything his drugs how much his on etc. Next is refer to skin specialist but thats too far get too. Last option is pts. I think do blood tests good idea to check him out first incase something in his blood.he said dog not well to do attack. Its a decision now up to us what we do at the end of day. So i will push for bringing dog in i feel confident in that."

her English in text is a little shaky but it sounds like she's going to try and convince her parents to agree to a blood test. It doesn't sound like she wants he hassle of a skin specialist even though the dog is insured.... If they don't do bloods then I guess they'll plump for pts. I text her back saying "ok now please ring the dog trainer" but she hasnt replied so no idea what she'll do next.

Perhaps it would be worth having your friend sign up here or another dog forum and make a post for advice? Some people just don't do well with situations they don't have a clue about, and perhaps having people say "I've been through similar, we did this, this and this" may help her? Maybe even if a rescue came along and offered some support. I know I was very overwhelmed at times with my previous GSD and her hip dysplasia and associated behavioural issues and thankfully someone in our puppy class was from a local GSD rescue and I managed to find her email and got in touch with her, just her offering to come over and help and tell me I wasn't doing so badly helped ease the pressure.
The parents being on board probably isn't helping issues - I know if one of my two bit my brother and he decided he wanted the culprit put to sleep, I'd tell him to stuff it, but I could afford to move out or tell him to move out if he didn't like it - if I was financially reliant on living with him then it would certainly affect the situation.

I'll suggest it but I'm getting the feeling she just wants to solve this quickly....I can see this ending in pts because it's too much hassle otherwise and I've been pushing her to call and have a friendly chat with my dog trainer for advice, I literally must have asked her 10 times and for sone reason she won't, so I think the odds of her joining here is low. But I'll try.

Maybe she is feeling a little under pressure, you say its to much hassle for them to look into it further, but maybe they have just faced facts and are trying to deal with what they have to do.

Although they are probably the problem the dog is the way he is , they are the ones who have to live with a dog they cant trust, any more,

No matter what you suggest, its their decision and to be honest I think you are best to leave them to make it.

No rescue is going to take this dog, and I agree with Rune on this, the only solution is for the dog to be PTS.

The sooner the better for all concerned!

Well if she doesn't want my advice she can feel free to stop asking. I'm not pressuring her, ever suggestion has been a reply to a text she's sent me.

I just don't see the point in bothering to medical treat this dog and not address it's behavioural issues. It's got to be all or nothing, either PTS or treat it properly. No point running blood tests and changing medications, they need to address the behaviour too. And as she's indicated they may attempt to treat him....why is pushing for bhaviourist advice wrong?

it isn`t, but you have to remember even when people ask for advice they dont always want to take it, your friend has her parents to consider and if they are not in for behaviourists or medical treatment, then your friend may feel under pressure for asking you for help, but not being able to utilise it,

I don't think Moons mum should be critised for helping. Whatever the situation, whatever the outcome.

If nobody 'helped' dogs like these, even if the end result is to pts, then not many dogs would be rescued. We all have to take a stand for these dogs, they can't do it themselves.

I agree,but rescue's are struggling at the moment,as was previously stated the fact is this dog has bitten and I can't see any rescue taking a dog that has bitten twice when there are thousands of dogs that are waiting for a rescue place that don't have a history of biting humans.
Even some DA dogs don't stand a chance of been rehomed,the rescue's don't want to take any chances.

We had a rescue dog,a dog which had been accessed or was supposed to have been, and was supposed to have been good with children,he attacked my eldest son.
The dog was PTS,that was our only option,no rescue would take him and if we could have found one which would have taken him he would have spent the rest of his life in a kennel,never been rehomed again,that's no life for a dog.

I agree, but sometimes , you have to just let it go and accept, your help is not wanted.

P.S, if this was my dog, he would be PTS, if I felt I could not keep him, I would not be passing the problem onto anyone else.

It may not be a popular viewpoint, but one I stand by.

I agree,infact been there and done it,as heartbreaking as it is sometimes we have to make tough decisions.
