How long can a dog be left alone? (And a dog with separation anxiety?)

Does my dog have separation anxiety? Signs, look-alikes and what to rule out
Chewed doors and accidents don't always mean separation anxiety. One question, a short video and a vet visit tell you which problem you're really dealing with — here's how.
12 dog separation anxiety myths — and what the evidence says
“They're punishing me.” “You spoiled them.” “Get another dog.” “Just crate them.” The most common claims about separation anxiety, checked against the research — with a verdict for each.
Training
Step by step, at your dog’s pace.

How long does it take to fix separation anxiety in dogs?
Weeks and months, not days. What the trials found (most dogs improved within 12 weeks), why progress zigzags, and how to spot a real plateau — or a sign to stop.
Dog barking, howling or whining when left alone: what it means and what helps
The sound your dog makes is a clue. Whining, barking and howling when you leave usually signal distress or frustration — and a bark collar punishes the distress, not the cause. Here's what to do instead.
Should you crate a dog with separation anxiety?
Crates are neither good nor bad — what matters is how your dog feels in one. Some dogs relax in a crate; others have confinement distress and panic. Here's how to tell, and what to do instead.

Will getting a second dog help separation anxiety?
It's one of the most common suggestions and one of the least reliable. Some dogs settle with any company; others need one specific person. Test before you commit — here's how.

Puppies, older dogs, new adoptions and more.

Most puppies protest being left at first. What the research says about crates, sleep, punishment and pheromones — and how to teach a puppy that being alone is safe, one tiny step at a time.
