I'm in total agreement with everyone - she is too small - he too large - GOOD LUCK and if you do get him neutered - you're making the SMART Decision here - your daughter wouldn't want to put her female at risk and she would be if they mated -
All the best to you - there is much more to breeding small dogs than people realize ....and you did really good to come here and ask BEFORE you went ahead and did this.
