Our family has a new puppy.(Now 13 weeks old) It is just like having a toddler. I need eyes in the back of my head.
We are getting on with the house training, but it is HARD work. I don't have small children though. We did not have animals when they were younger, because I just don't think you can trust any dog (or cat) with very small children.
I wouldn't be staying at anyone's house with our puppy just now, because that wouldn't be fair on the host or the puppy. She can mostly hang on long enough to go on short visits to other peoples houses , but still has the odd accident.
And we are stopping her from eating dried cat's poo,if she finds it in the garden,(and if we see her find it).
I am also not a person who freaks out at a bit of mess. My children, now 13 ,16 and 20 have always been very healthy children, partly, I believe, because I was not obsessive about 'hygiene'.
Life is for living, not to be scrubbed down, sterilised ,covered in 'anti-bac',or avoided altogether.
But that is just my opinion.
