I just want to say this: just because I do things differently with my dog than you do with yours does NOT mean what I'm doing is wrong or that I'm a horrible person or know nothing about dogs! I've had dogs my entire life and never had issues! My Dobe is the FIRST dog I've had that did the submissive peeing and as I've said she no longer does it even when being scolded or "punished". You all need to stop being so judgmental and give support!!!!!!! That's why this site is here! Maybe some of you should do your own research on submissive peeing or go to vet school!!! we did what our VET said to do and it worked compared to what some of you said that didnt work! Just saying!
Miss Red, I have been reading and checking out DT for quite a while now and do understand how you feel this way.
The biggest thing to remember with some posters on here is the fact they really are truly trying to help, but sometimes it just does not come out the right way.
My personal view on your OP is this:
My Dachshund growing up constantly submissively peed, and she never really broke out of it.
Sometimes it is fear, sometimes it is a way of showing they are submitting, and sometimes it is just an excited reaction.
Biggest thing to remember with puppies and especially Dobes, they function and strive off of confidence. I am not accusing you of being to harsh or not doing the right thing, just do keep in mind, some are more fragile minded than other, and I've noticed especially females are that way.
Maybe just cut off "Ruby Red" all together for a while and establish that confidence/trust level with her again, and it also may be a fact of age as well.
Either way, dogs will be dogs, and every dog is different, so just keep working and trying something, and usually something will end up working!
