How to stop my Labrador from repeatedly chewing the dog door flap?
Unfortunately there isn't a quick and easy solution to your dog's weird obsession. You can try spraying a product called Bitter Apple or No Chew (look at the pet store) to deter him from chewing there. Also make sure he has plenty of other (and safer!) things to chew on. If those don't work, you may consider crate training or training him to wear a basket muzzle to prevent him from getting in trouble when you are gone.

Training & Behavior
My dog chews his crate blanket. Why does he do it and how to stop?
Dog behavior can be a little mysterious sometimes, but chewing on a blanket can be dangerous, especially if small pieces are ingested. These can cause a foreign body obstruction, which can be life threatening. You can try getting Kyro a cushion, that may be less tempting to lift and chew, for his crate. He may also feel anxious being confined in the crate, if it is too small. You can try fencing off a part of your home for him with baby gates. I hope this helps and that all is well!

Vet Q & A
How do I stop my dog from barking, biting, and running out the door?
It sounds like Fluffy is reactive and uncomfortable around people he doesn't know - this is a very common problem. I would recommend asking visitors to call ahead before arriving, so that you can put Fluffy in a separate room or a crate before they arrive. Once they are in and settled, you can bring Fluffy out on a leash and practice rewarding him with tasty treats for being calm. The front door needs to be better managed so that Fluffy cannot run out after people who are walking outside. If household members are not able to remember to close the door reliably, get a baby gate or other barrier to use as a back-up so that there's no way he can run out. Separately, to work on this problem, you can practice standing just inside the door with Fluffy on a leash, and feeding him treats every time someone walks by. Over time, he will learn to look at you for his treat when he sees a person, rather than wanting to chase them and bark. It can be difficult to do this on your own, do I would recommend getting in touch with a veterinary behaviorist or a good reward-based trainer who can help you in person. You can ask your vet to refer you to a qualified professional in your area.

Food & Nutrition
Preparing for dog recovery: small crate cost & regular food?
That's cool that the recovery suit will work for her then. The cost of crates vary by location, so I would check costs in pet stores, as well as checking online sites that resell things (like Ebay if you have that in Bosnia & Herzegovina). You may be able to buy one second hand. Yes, she can eat her regular food :-)

My small dog is afraid of the electronic dog door. How to train her?
I am sorry you are having trouble with Midna! It may be that she needs some extra time and attention to learn this skill, and unfortunately there are no guarantees that she will ever get it figured out. I would try teaching her separately from the big dog for a while. See if you can get her to do it without the bigger dog around, then try to get her to "wait her turn," after the bigger dog goes through so that it doesn't whap her in the face. Best of luck to you! Thank you for asking Petco Pet Education Center, formerly Petcoach!
