“Some specialist toothpastes for human-use contain ingredients which are unsafe for pets, for example xylitol, an artificial sweetener that is very poisonous to dogs.”

Some admitted giving their dog chewing gum when bad breath struck, while others thought a haircut would purify the scent.
There were also respondents who thought their dog’s unsavoury habits might be the root cause – and sought to keep toilet lids firmly shut to stop them drinking the water.
