Thank you for your question
My nam eis Clare
I shall do my best to help you but I need some further information first
How long have you been separated
How bad was the bite?
Did it require medical intervention?
It is an arguable point.
Personally I would say that a dog bite should be mentioned because of a posisble fear of dogs developing and because I regard it as a serious minor injury.
However you would not expect to be informed of every minor injury and there is no list of what falls which side of the word "minor"
This is an area that needs to be discussed between you - possibly within the creation of a Parenting Plan - and consider using a Communication book for minor incidents such as this which might be forgotten by the following Friday
You can read more on this website
Please ask if you need further details
No bother at all - I am glad you see a way forward
