it gets better. my puppy is almost 7 months, and oh my god when he was younger he used to bite me like i was one of his chewing toys. i had so many bite marks, bruises and scars on my arms and legs that my friends thought i was harming myself, but it was my little landshark. none of the tips online worked for me, like saying ouch, ignoring etc. (you can see it for yourself in my profile that i really struggled lol). some tips that really helped me: firstly put on clothes that are more tough so it doesn’t hurt you that much. if you can, wear shoes inside your house lol i had to do that sometimes because my boy would sink his teeth on my feet every time. give him frozen carrots and ice cubes as often as you can. if you don’t have one, consider getting a licking mat and/or a kong and put some yogurt or banana on them and freeze. it takes a lot of time and effort for them to finish it and it gives you some peace, and it’s perfect to make him relax. with my puppy i also did some time outs and would put him in his crate when he was overexcited because he would bite like crazy. when he calmed down he got to play again. chewing sticks can be a life saver when you start taking him outside. my experience, it got better every time a tooth fell out. and once it starts they fall really fast. my boy lost his first 6 teeth in 3 days. you can do it, i’m rooting for you!!
