Great to meet you and welcome in! Sorry for your loss, it’s particularity hard when you lose one at a young age. I have had some tragedies as well but I don’t let that stop my love of the breed i am just much much more careful now when selecting a breeder now. I will not get anymore puppies from backyard breeders only breeders that are doing health and genetic screenings they cost more but are worth it. Even with breeders that are screening you have to still be careful so it pays to do research. Good luck finding your new friend when you are ready I just can’t imagine my life without a Boxer in it!
