It’s part and parcel; when you buy food – buy bones and toys, too. Plastic bottles work, too, but they love real bones the most. Keep your shoes far, far away.
When you catch your dog chewing on the wrong thing,say,“No!” then replace the object with something more appropriate to chew on.Praise when they do the right thing.My last three dogs have been GSDs.They’re the best :)
Dogs are so called puppies for approximately 2 years. It’s their nature to chew, especially as a “bored” puppy. They have lots of energy to burn. Make sure he/she has plenty of things they are allowed to chew on. Rawhides that are their size and also not too small for them. this usually helps allot. My motto for my Yorkies is “they can never have too many toys.” They like to tear some toys open and get the squeaker out, then incapacitate it completely! That’s alright with me. It’s their toy & they can do what they want with them. Don’t ever try to fight a dog’s instincts unless they are being destructive to your property!
The real problem is not getting enough exercise, but I understand the dilemmas of a busy life. That’s why they get bored, they aren’t tired & have to be busy. I don’t believe in crates. I like to tell people, “you hold your bladder & bowels for 8 hours or more.” It is twice as hard for puppies small organs. I do believe in a restraining area, like a pen or a gate across a door way & such. Then some pee pee papers. Animals can get sick too you know. At any age of life like people. I’ve had 8 Yorkies, various large dogs as a child and at one time 5 dogs in the house together and behaving great. Good Luck.
Puppies teach you to be neat and tidy. Keep your stuff up high where the pup can’t reach it and @zen_ has it right, keep plenty of raw meaty bones lying about, I guarantee your dog will prefer them to tasteless old purses.
At the 7 dog years to one human, your dog really is still very mentally immature so it could go on for some time. Do you crate him when you can’t be watching him? That is an excellent solution also.
