Dogs have emotional difficulties during puberty.

A new study has found that canines go through a similar experience to humans as they reach adolescence.
The findings from Newcastle University reveal that dogs in puberty are half as likely to follow their owner's commands than a young pup.
Dr. Lucy Asher, co-author of the study, feels that dogs mirror people by showing their rebellious side during puberty.
She wrote: ''Generally teenagers that have a less secure relationship with their parents are those that are more likely to show more conflict behaviour towards their parents.
''That's the same finding we have (between adolescent dogs and their carers).''
She added that some breeds begin puberty aged between six and nine months.
Writing in the journal Biology Letter, she said: ''We know that there are hormonal changes and we know there is a big reorganisation of the brain that occurs around that time across mammals, so we are fairly confident that is something that is going on in dogs.''
