are you turned on by the smell of dog cum/precum? i want to mate with my dog more often but the metallic smell is really gross to me. perhaps there are ways to mask it?
Minus waste and farts lol, I cant find fault in any of the smells from dogs. Like all things in life its rather subjective. I love the smell and taste but it does very on diet, breed, and age. There was a chesapeake bay retriever from my child hood with the best tasting cum. I had trouble letting him on my back... I just wants to drink him up. My first dog ever was a yellow lab who was way more musky than any dog I've gone down on but like I said for me its all delicious.
I would suggest tweaking his diet. My own dogs eat a raw food diet and from ass to mouth or male to female they have a better all around scent and flavor plus the added bonus of healthy lover and companion.
on a more serious note tho, i might have "bad nose" or something because i honestly have no idea how it smells like or maybe it's just not that noticeable to me (compared to smell of my ejaculate, which i don't like very much for example). my current boy asks for head once or twice a day and i never really noticed how it smells and there definitely were times when we finished and i had some on my face. or he shot me in the eye as i was maneuvering his penis behind him through his legs. it's not a nice thing to have in the eye . or that one time when i had him in my throat almost to the knot and he farted directly in my face.... turns out i do have a gag reflex.
With the exception of one dog, I always had to be deliberate about smelling it. That little guy was super stinky/musky. The others smelled mostly like sea water - salty. I love that smell, so I can't relate to your feelings. If you can smell his cum without really trying, he may be a stinky one. Changing his diet may help, but I wouldn't count on it.
I absolutely love the smell of my dog's penis and knot. It has pretty much always smelled nice even after a few days of no sex. The metallic smell is arousing for me.
If you want to decrease the metallic smell of the penis, suck him more often.
The cum at least for my dog does not have any strong smell and I barely ever smell it unless I collect it and smell it on purpose.
