If urine from a dometic dog in heat will work for yotes then will urine from a domestic male work for scent post for yotes?

Maybe so in most cases but I never believed in it. So many coyotes in my country have been chased by dogs that some might avoid any odor of dog.

Good point ASA, we have alot of that around here too.

I once bough a male wolf pup from Ardell Grawe.

When it was growing up it would squat but as it got older, it starting to raise it's leg to urinate.
I would take it on a walk and when it would stop and hike a leg, I had a clean wide mouth jar,(used to be a peanut butter jar) and I would kneel real quick holding on the lead with one hand and hold the open jar under a stream of urine with the other!

Got my wrist soaked a number of times but I got pretty good at getting about 50-90% of the urine.
I know this sound funny and to many I guess it is...but, it worked and I collected a whole bunch of urine that way!

I fresh froze it and used it on foxes.
Worked real well and even caught coyotes, 'coon and even a badger at a set using only wolf urine.

I have used my meat (carcas) fed husky droppings at coyote flat sets with excellent success.

What does this have to do with the question?
Nothing...maybe everything!

I was even thinking that when they urinate scoop up a little of the soil, grass etc. and put in a bag or the bark off of the tree etc.

Back when it was available in the olden days, I used a lot of timber wolf urine on fox, coyote and bobcat sets.

One of my old time mentors, a man by the name of Frank Morgan, always had a hound tied up. He dug a hole and put a bucket there with a bit of coyote urine in it to get the dogs use to using that spot to urinate. He was one of the better trappers of his time, and about the only lure he ever used was dog or coyote urine. He always had a male hound, and rarely fed them meat, except during deer season.
