I just adopted a 5 month old....something mix. Maybe yellow lab and shepherd, no one really knows, that's the beauty of rescued strays I guess. He's already at 36 pounds so he'll be a pretty big dog. He's a good boy but he's teething, so he gets into aggressive fits of rage where he'll start biting me and running all around the house destroying what he can, until he settles down. I have tried everything I could find online to get him to stop, but it doesn't work. Toys will distract him for a couple minutes. Frozen kongs with treats and peanut butter inside will distract him for a bit longer. Yelping loudly as suggested by some does not work at all. I've also had someone suggest I just stand completely still and ignore him and he'll stop, but that's easier said than done when you have a big puppy with sharp teeth biting into your skin. If I start pulling my hands and feet away, he thinks it's a game and that only encourages him. I have cuts and bite marks up and down my hand and arm from him. Eventually, he'll wear himself out and settle down, right now he's napping quietly. I was 10 the last time I had a puppy who was teething, so I don't remember much, but I don't remember her biting. She would chew anything she could get her mouth on, but never people. This guy though likes using human flesh as a chew toy. Any suggestions, or is it something I just have to deal with until he grows out of it?
