That's what I've always thought- but no one's ever really believed me and told me not to worry about it (through three basic obedience classes and two agility, three trainers together). She's done this the entire time we've had her. When we first got her, you couldn't touch her- she'd run away, so NO idea what sort of early experiences she had.
Ok, good. If she has always done it then it's not usually medical and you have ruled out medical problem. The fact that she couldn't be touched or handled at all initially tells us alot. I am getting the feeling that touch is aversive to her. Honestly, the other trainers just may have not known. I know a lot of trainers who can train but aren't as skilled at reading body language and interpreting it.
Medically, there's nothing wrong with her so far as anyone can tell. She's a fairly reactive dog who picks up on things FAST and behaves better when we're in training for something (anything!) She's smart and has endless energy, she's also ball crazy.
You probably know this but I will tell you anyway in case you don't When the cognitive (learning) side of the brain is working it is more difficult for the limbic (emotional) side to work (and the other way around). This is why they tell people not to try and talk when they are angry. You can't do it. When she is working she is less emotional. I have an extremely reactive, highly fearful cattle dog, if I engage him BEFORE he goes off, I have him, if he goes off first, I can't get him back. I spend A LOT of time scanning the environment and being hyper vigilant to keep him from exploding.
My family (who she lived with up until 2.5 years ago) thought it was just funny or weird and my mom would get her going and called it 'purring.'
I have mostly ignored it and really only pet her head, cheeks, under her neck, and her butt since those elicit less reaction. I cuddle Topaz when I need dog time.
Not so good, as I don't think it was "purring" I love that you have been able to identify the specific areas that trigger the growling. Thank you for getting the cuddles from Topaz as so many owners would try to force her to be something and someone she isn't
She tolerates very slow, light petting fairly well, but if you treat her like a normal dog, you get the growling. I've done some clicker work with petting her and got to the point where I could pet her three or four times without any negative reaction, and there was some carryover between 'working' and 'relaxing' behavior.
I like this, I might try this too. You could also do some straight classical conditioning where you pair the gentle petting with something HIGHLY reinforcing like very high value food. You could also use the ball but I wouldn't do it at the same time as the ball may create some play growling. But, you could do a few pets and then throw the ball so that the petting becomes predictive of the ball. I would use food too if you can. I would do this with the very light petting that she tolerates until the gentle petting creates a very relaxed, happy face and loose body before going to harder touch.
Part of the trouble is, if she's working/training/focusing, she doesn't react the same way and is much more tolerant. Same if we're out on walks, etc or there's something interesting to smell or look at. Distractions make her react less to the petting? I'm not sure how to condition the relaxed behavior when doing training changes her mindset so much. Just repetition?
It could very well be that if she is uncomfortable in the environment she just simply has "bigger fish to fry" in that she is watching the environment and becomes less vigilant with you. If she is uncomfortable with the environment and you see any signs of stress or anxiety I would not pet AT ALL because she has enough to worry about. However, if she is relaxed and happy outside then pairing that and some food with petting might be a good idea.
That makes sense to me.
I've always wondered if a) she just doesn't like touch so I should just avoid it b) something about it makes her anxious so I should try to change it or c) if dogs can get hyperaesthesia like cats and actually find touch uncomfortable
I think that she doesn't like touch. I think it is aversive to her or at least makes her uncomfortable. I would desensitize her to it, very slowly, little bits at a time paired with something she LOVES.
I'd like to get her to be less space-guardy with the cat (I thought that was what the issue was, but wanted another set of eyes) or just more relaxed around him in general, but not sure how to go about it. I taught her to 'go get the cat' and she'll go up to him, and be near him happily when it's an activity, but not when it's just hanging out time.
More desensitization and counterconditioning. The cat means good things happen for her
Here's a kind of scary clip. She looks like she's going to eat me. She chooses to start barking rather than eating people though, thankfully (especially for my family. Ugh.)
YouTube - MVI 1113 I do not normally pet her like this, because I KNOW she reacts this way, but I wanted to get a clip of it.
Yes, very scary video Multiple tongue flicks, whale eye, stiff body....
The great news is that 1) she has a compassionate and skilled owner who cares about her and what is going on with her and that 2) she has always chosen not to take it a step further with a bite. I always tell people with growling dogs to thank their dogs because growling is information that tells us that the dog is not comfortable. If a dog doesn't growl, or worse has been punished for growling, then they don't growl, they bite and that is much more difficult to modify
