Bronx looks well loved and very spoiled, what a lucky little boy he is to have you for his new momma, he is just adorable. BTW, I love his name, I was born and raised in The Bronx, NY lol. I have always loved that name for a pup.
In the USA our dogs must stay on heart worm preventative all year. Before we can get another round of pills our pups have blood work done to make sure they don't have heart worms before our vet will give us a script for another year. Always better safe then sorry
