And no social services wouldn’t assess when nothing has actually happened and the majority of these dogs do actually live as happy well adjusted family dogs.
@annevalentine This isn't correct. Safeguarding does not just cover situations where a child or adult has been harmed. It covers risk of harm also.
If the OP raises a safeguarding concern with children's social services the fact the dog has not attacked anyone yet is not relevant.
SS would need to assess the risk to her child.
What the outcome of that assessment would be can't be predicted given I would assume lots of factors would need to be considered
(such as where the dog could be contained when the DD visited). But I think it's fair to say that bringing such a dog into the home with a young child without some serious risk mitigation is not going to be considered appropriate.
You also seem to misunderstand the issue where families already own these dogs and equate that to the OP being unable to do anything about it.
Where parents have made (the stupid) choice to own such a dog they are in agreement about it. Neither is going to look to SS or the court.
In this case the OP is not in agreement and is perfectly entitled to raise a safeguarding concern - which is precisely what I would do in this situation.
The age of the child is also relevant. At the age of 11 she is able to articulate that she does not want to spend time with her father if he has this dog. Given the dog in question if this went to court I think you'd find this was a perfectly reasonable position to take.
The mother and child do not want to stop contact with the father. They want to stop contact with the dog.
Ergo it's the father undermining access and not the OP or her daughter.
