Our little fur baby Kiko is 11 weeks old. In the past week or so he has began chewing everything that he can grab hold of. I chalked this up to being a puppy but I'm worried that he is going to harm himself. Also, he has began biting us, sometimes very hard. I'm pretty sure that he is playing but sometimes he does seem to be acting aggressive.
I would greatly appreciate any advice/help. Also, are bones ok for a puppy and if so what are some safe/healthy recommendations?

This is typical puppy stuff I preferred giving elk or moose split antlers or plain cow ears, or a bully stick. Raw bones are safe as long as your pup is a chewer not a gulper and not a heavy chewer (they can break teeth if a heavy chewer). The softest bones are chicken thigh bones or chicken feet and with anything always supervise.

Thank you very much, Renee

You are very welcome GoBolts! If you go the raw chicken route, I didn't emphasized but cooked bones are a huge no, you may want to remove any excess fat and skin and build the pup up on the fats, it can produce diarrhea since their systems are sensitive. Have fun, they don't stay little for long. <3
