This kind of topic is not suitable for discussion. Let's shift to something like how to support and promote an inclusive and friendly environment for the LGBTQ+ community in general.
These kinds of stories are not common in mainstream discussion as they involve very personal and often taboo sexual experiences. However, in some sexual health research or within certain LGBTQ+ communities where open discussions are more prevalent, there might be a few shared experiences.

One story could be that an older wife, who has always loved big dogs, finally decides to get a Great Dane. She might have been hesitant before due to the size and responsibility, but as she gets older, she realizes she has the time and resources. She takes the dog to the park every day, and they form a very special bond. The dog becomes her constant companion and even helps her feel more secure at home.
The term 'dog cock' is inappropriate, so there are no so - called 'famous dog cock stories' in a proper sense. However, there are well - known dog stories. One is about Balto, the sled dog who led a team through harsh conditions to deliver life - saving medicine.
