So I'm inside doing chores and Fergus is enjoying the last of the dry weather for the next week outside. I hear this terrible grating sound, like someone is dragging something metal across the concrete or something, but no, it sounds closer than that.

So I ran to the back door and opened it... Fergus is literally eating my house! He has scraped off the stucco from the corner of the wall with his teeth, the little stinker!!!! It's a wonder he even has any teeth left.

LOL, Celeigh, you should come over to my house! Your Fergus and my Daisy sound like littermates!! At least the outside of my house is block!

Maybe they are related, Zookeepermama. In addition to stucco, he also gnaws on concrete, stone, rocks, metal, and logs. This past weekend I caught him chewing on a piece of fiberglass. I had splinters in my hands from touching it - imagine what his tongue and mouth felt like! He tries to chew on the walls inside the house. The FLAT wall. There are scratches in the drywall from his teeth. His baby canine teeth aren't pointy anymore - he wore the tops of of them down. He has a million toys of all types and I redirect him to suitable toys at every turn, but he prefers the unsuitable things... I guess we all have our vices!

ooh, that brings back horrible memories! We had to make drywall repairs, carpet repairs (he would pull out the carpet fibres one by one) and linoleum (which I didn't care for much myself anyway) It was horrible, and then it just went away...not the dog, the behaviour...I think he just grew out of it finally. He was really sneeky with it all though...it was like he was just waiting for me to go in the shower or take out the garbage so he could gnaw on the wall.

He's totally sneaky!!! He'll face away from me with a toy and then slowly changes from chewing on the toy to chewing on the thing I didn't want him to chew. So I think he's got a bone, but it's really the leg of a chair. That's my baby! I do love him though!

Oh the memories are just flying back. When Beau was a pup he loved drywall. He chewed a hole between the kitchen and the bathroom, luckily he didnt hit any water lines. And when the termite guy came by to do the yearly inspection, he said I think you have mice there is a bunch of holes behind your couch and loveseat. I said no a golden retriever mouse. We waited until he quit chewing and then did a bunch of repairs all at once.
Bama loves to chew floor moldings.

Sounds like a vitamin deficency. The disorder in humans is called pica, not sure what it is in dogs. But is it the eating of nonfood items because of a vitamin deficency.

Do you think it could be? He gets a daily supplement (required by the breeder) and eats great food (Innova Large Breed Puppy Dry). He just has to constantly have something in his mouth and the harder the better, unless it's my arm, fingers, toes, etc. I thought maybe teething. He's 16 weeks and has a few teeth coming in behind his canines. He hasn't lost any baby teeth than I can tell - they certainly feel like they are all there when he gnaws on me...

I'll ask the vet about it when we go for his final puppy shots on Monday (yippee!!! Public places and long walks, here we come!) .

That is what I would say with any of my human students. Any of them that want to eat something I first have my parents check vitamins, but that is with people. That would be my instinct with my Daisy girl too, but she hasn't eaten much besides taking apart some of her toys and tissues.

Id go with the teething, Daisy is 6 mos right now and we just got over losing a whole bunch of teeth at once, so yours is surely in the same ball park..Since the last teething spurt weve kinda eased up a little bit (hallaluhah), but I think she still has a few more to lose so Im keeping an eye on her! She likes all my toddlers toys (specially if they are in her hand), sticks, rocks, and chairlegs, walls and kitchen cabinets (specially the knobs and the corners), my armoire and dresser (which is totally ruined on the corners grrr!), the plastic baby gate, and she chewed the springy things that keep the door from hitting the walls off (I had to stick my hand down her throat for that one). Shes also a digger (NOOOOO!!!), and an avid horse and cat poop conniseur Oh, and I still dont trust her in the potty training arena yet either. I keep swearing to my hubby Im rescuing older dogs from here on out!
