I absolutely do, coyotes are very territorial towards red fox especially. Even at natural scent markers. I see it in the snow all the time here were a fox came thru first , the yotes always kick scratch at red fox scent marks.
Red fox Urine smells stronger throughout all temp ranges, even down to zero. Here's a test, freeze red fox and coyote urine overnight then smell both in the morning. Your welcome

Is that bladder urine or store bought? All store bought urine is not created equal.

I always figure It this way. A fox approaching a set where coyote urine has been used isn't going to back off since It can plainly see there Is no coyotes there.
The only reason I use coyote urine Is because we have NO fox. But I did notice when trapping In areas with all 3 species that GOOD cat urine seemed to work better then either fox or coyote urine when trapping fox or coyotes.

both Beav, no diff..

I'm tending to be more like The Beav, but one flaw trappers continue to demonstrate (IMO) is they always want to treat every coyote or every fox, the same as every other coyote or fox. THEY ARE ALL DIFFERENT. Just like all domestic dogs are different. Some are aggressive; some are passive; some are skittish and some are not. Different coyotes have different experiences they bring with them to any given stimulus; different seasons/times of year bring a whole new shift as well. Not EVERY coyote is going to act exactly the same.

Craig O'Gorman uses (if not owns the patent on) the word neophobic in relation to coyotes. The word means "fear of the new." While MOST EVERY coyote fears things that are new, given their age, sex, time of year, prior experiences, etc., their level of fear or their response to the stimulus will be different. Why do trappers have great luck with fatty meat baits in early fall but later switch to gland lures? Because coyotes in the fall are trying to consume calories for winter reserves; in the early spring they start to think about territories, mates and breeding.

If a coyote has smelled your collection urine several times because you left it behind when you pulled your trap, then he/she might be accustomed to it so when you go back next year and put a trap down, the coyote is already familiar with that odor and has no fear of it. On the other hand, if its urine (from whatever source and no matter if its male, female or mixed) the coyote has never smelled before, he or she GENERALLY is going to come in down wind and make a careful inspection of it. He may only come close enough to satisfy his curiosity for the moment and go on about his business because he's got other things on his mind. If you observed all this (in the snow perhaps), you could possibly conclude that the urine wasn't any good, wasn't attractive, etc., but the fact is, your coyote just wasn't in the mood at the time. Next time down the trail, he knows your urine is there and may not exhibit as much suspicion. Maybe this time he's more in the mood to check out the source of the urine and he comes to check it out -- but you've pulled your trap because you interpreted his response the first time as bad urine. Or maybe you decided to add a different lure/odor to the set and now the coyote is really confused by the sudden addition.

Who was the fellow on here some months ago that had the pet coyote? He took some videos/photos of the coyote when he'd take her on walks in the neighborhood. This coyote had never been around traps, hunted, etc. but was very suspicious of anything NEW. Many young female coyotes have that same trait. They don't have the testosterone of a male to be bold enough to make new discoveries and they are often not as hungry as more active/aggressive males. Anyway, this coyote's response to anything new was suspicion. However, after several encounters with a new object in her environment, she began to trust the object and would start exhibiting curiosity.

Anyway, enough said.

Well said

Very well stated Laz, that's the reason I try different lures every season. And I don't use as much urine as most. I change sources for urine also. Ya know when you have a winning combo when you trap as many girls as guys or more.. Techniques get tweaked too..

Very well said Lazarus.
Back in the early '60s I had a pet (had two day old pups to start, one was killed ) coyote for about 3 years, the single important thing to remember about coyote behavior is that they are cowards; always afraid and keeping every thing at a distance, not only new things but most things. They overcome that fear for hunger and for curiosity, he was very curious, in a cautious way. That coyote pup loved fresh milk but was scared of the pan I fed him in, all the time he was with me he would circle that pan of milk then dash at it and grab a bite of it as he ran past, then repeat, twice a day. Never did learn to lap it, because he was always afraid to stand by that dish in the open - something I only realized years later.
Another little thing that I rarely see mentioned about coyotes is that he hunted with his eyes much more than with his nose, he'd see a ground squirrel over a hundred yards away and key in on it. Same with pheasant. His approach was always a semi circle that put him down wind for the last 30 yards or so, then his nose took over, but as I think back I don't recall him ever going more than a few yards to a wind smell that caught his nose, like rabbit burrow or bird nest. Observations of a 12 yo as recalled many years later, so...

People all want the degree, but not the homework. Test sets, cameras, study the animals not the computer screen. Not hard to test urine with cameras and see what's happening. How do you think Tracy got his PhD.

Bwahahahahah! School of Hard Knocks

Either way I believe u have it

Left lane that's part of the problem.... been stuck in dump truck for two days hauling rock. I get cranky after too many days doing real jobs...

Thanks, for the information. That's why I asked.

Always used fox urine at my coyote sets.

In my experience there is a huge difference between quality urine and low quality urine.

But beyond that I can't tell a difference at sets. There doesn't seem to be a rhyme or reason to what type catches more of what animal. I just see it as a smell to add to a set, or not add. In my mind I see multiple variables that go into a set so I can't pin success on the addition or subtraction of one item. It's just a system that will work a percentage of the time, hopefully that's a strong percentage.

I know people will disagree with that but its what works for me.

Coyote urine at coyote sets. But I often use different brands of coyote urine. As Beav said = Not all store bought urines are the same. I use several different urines as I set up a property ,im trapping on. Laz . What about urine habitualization? I have seen it with lures. WHY not with urine? Im take the following urines with me om 4000 acre job. O gormans = Boss Dog . MTP coyote urine . Some SMC from a secret source! LOL! And some Wolf Urine from Ogorman. Will rotate urine as I set traps.

Leftlane .You are correct. Not thick at all . From bioliogist in Alabama. 1 per 640 acres = AS compared to 6 to 8 or more in South Texas per square mile. So places that I trap 2 and 3 times a year. Even though they are 30000 acres you may only have 1 per 1000 acres. 70% percent of my trapping is maintaince work. These places have on staff Biologist . The Biologist are happy. They have been asking me back for 5 years now. So I feel like im taking 80% plus of the coyotes per trip. I have other trappers around me on smaller tracts . So even in a low coyote population. I try and take care , to switch up urine and lure. I worry about Habitualizion .SO my thought is = over kill may be better

Couple questions from a entry level canine trapper........

How is canine urine collected.........I know how easy it would be to collect mine...but canines? In volume?

I've always heard references to "good" urine? How does one qualify what is "good"?

Where do I find the good stuff? Seems every trapping place on the planet......plus some others....all sell urine.
