Do you think it's safe to re-use old dog toys and do I need to clean them in any particular way before giving them to my pup? My parents still have a large basket of dog toys from their last two dogs and I am hoping to pass age/size appropriate ones onto my puppy but wanted to check it's safe first. Both previous dogs were up to date with their vaccinations, flea/worm treatment and had to be pts because of non infectious conditions (cancer and heart failure). I have put all the cuddly toys through the washing machine and washed all the hard toys with washing up liquid (all thoroughly rinsed) so they don't smell of the other dogs anymore. Do you think this is sufficient? I know I'm probably being overprotective but this is my first pup and I don't want to put him at risk. Thanks for any help.
