Just adopted a dog.... is she vulnerable to coyote attacks???????

No one was rude. People just answered the question! Enough backbiting!

Folks, and this is for EVERYONE replying on this thread...this person asked a question, and you can give info and suggestions, without the theatrics.

Thank you.

Houndlove said coys are "Scary smart" and that's what they are. Much smarter than most dogs. Probably all dogs, actually.

I once saw a band of coyotes approach a pasture where I had sheep. At the time I had my older female Lu, Tully was a puppy (about five months old), and I still had the puppy's sire Strider. The coys split up into three groups. One shot down the back of my property and drew the big male about half a mile away. Another group attacked the back fence and drew my female off to meet them. A third group circled right around on the road and approached my sheep from the front. I don't know whether they didn't see the puppy or didn't think he'd be a threat, but they started to go under the fence. At that point, the puppy sounded the alarm. Strider had apparently dealt with the ones in the far corner of the property and came up the field like lightening. Tully, the puppy, was facing down two coyotes and I don't know what would have happened if I hadn't then started yelling.

The astonishing thing is that all this happened in about ten seconds. That's how fast those coyotes figured out a plan and put it into effect.

That's a good example of luring. The same thing happens, by the way, when they attack a group guarded by donkeys - except the donkeys have no instinct to stay with the flock. The guard donkey concept works not because they feel bonded to the flock, but because they are territorial and just plain hate canines. I can't use donkeys here because I work my sheep with dogs. I'd have to remove the donkeys every time I did something.

I can understand a newbie wondering if an adult dog could fend off a coyote whereas a puppy could not.  But, the plain and simple answer is that an adult dog can be a victim, too.  To be honest, I keep an eye on my dogs even if the three larger ones are out together in the same pen.
Coyotes are *not* exclusively nocturnal.  They tend to be more active at dawn and dusk, but it is not unusual to see them out during the middle of the day either.  They don't mate for life, but they may stay together for several seasons.  They don't hunt in packs, except when the adults are teaching the juveniles to hunt, so when you see 5-6 together, it's usually a family group.  They regard dogs as intruders on their territory and will kill them because of that, or for a meal.  No dog  should be left alone and unsupervised, in e-fencing, penned or tied, in coyote country if you want him to stay alive.  A fence must be six feet high and three feet deep to discourage them, and some of them are like BC's and can climb.

Just food for thought for everyone on here:  My aunt had one of her mini dachshunds taken my a coyote.  The dog was not an outside dog, but they had just been let out to go potty for a couple of minutes and BAM, that was it for Kelly.  I was listening to a radio show out of Chicago recently where the subject was coyotes.  One caller who lived in the suburbs and said his wife witnessed coyotes carry off their Bichon in their backyard minutes after being let out to go potty.  It can happen to indoor or outdoor dogs.

The best bet IMHO, is to keep the dog out of reach of the coyotes at all times when the dog is not being directly supervised.  It is easiest to accomplish this by having the dog indoors at night and when you are not home, and be near the dog when you let her out at night.  If she must live outdoors, then it would be best to keep her, at least at night, in the garage or in a coyote-proof shed.  If this is not possible, then I would recommend a very strong kennel with a very strong roof.

Since the coyotes now know that your place is a place where they can get a meal I would just expect them to be back at any time and protect your dogs accordingly.
