I am a full-time university student with two boxers I am married and my husband is military, meaning he works 16 hours a day. I got my first boxer over a year ago from rescue because I needed a companion. Rogue is awesome, then one just wasn't enough so when we moved into our house I bought a new puppy Sunni. Anyway, I love both my babies equally and immensely but Rogue was easier. He was housbroken, and had all of his shots when I adopted him. He was a quick learner because he had a longer attention span, and he was eager to please because he knew we loved him. My female I had to potty train and we are still trying to get her stubborn hide completely obedience trained. She has never had to deal with the heartbreak of rejection like my boy has so she doesn't really worry if we get frustrated with her. I agree with other posters you have to make the time to spend with a dog, not just exercise and vet appointments, but plain old petting and loving. And the cost is very expensive the first year wih all of the stuff you have to buy, and vet appointments, etc. Plus if you rent you have to make sure that the owners are cool with you getting a dog because they can make you get rid of it or evict you if they aren't cool with it. I suggest you find these things out and research about boxers before you make any steps. There will always be boxers out there so there is lenty of time to research. Then I would suggest rescue in your area. You will be giving a dog another chance and they will be grateful more than 100 times over, also it is much cheaper if you get an older dog as you only have to get shots annually.
But I have to say I sleep better at night hearing their snoring because I know they are good guarddogs, and no one is going to sneak into my home. They are good friends. Basically they are family. The decision to get a dog has to be yours alone, but please make sure this is what you want and can do because there are already so many dogs out there that were given up because their owners didn't really think through the consequences of having a dog. But I know you are not like tha as you are already researching by asking us the boxer parents. Good luck.
