My 7 months old Rottweiler has a serious biting problem. Also, he can not get down from even low heights. Kindly help

Encourage your pet to chew the thing you want him to chew. Never offer you to chew on. Make him busy to play with some interactive toy such as treat dispensing. The squeaky toy is great to catch the attention and to play fetch. you can also offer him some chew toy to chew. make your puppy confident, lack of confidence make the puppy fearful, shy and hate meeting other dogs and people.

Its not late, u can still teach him not to bite... May be ur dog only listen to one member of ur family, so let that person spare some time n teach her not to bite.. They r smart dog, they wil learn soon enough.
