Had a beagle growing up. He lived for 17 years. Have a beagle mix, right now. He just turned 4. Unlike some of y'all, I LOVE the beagle bay. It bothers me not in the least. Sadly, my current hound appears to be mixed with JRT and he has a high pitched JRT yap. He can't bay or howl worth a darn.
Beagles are a lot smarter than people give them credit for. They have excellent problem solving skills. They can learn anything. The difference between a GSD and a beagle? The GSD wants to please. The beagle wants to know, "What's in it for me?"
Most, but not all, beagles are very food motivated. Obesity is the number 1 beagle health issue. Food needs to be measured out. No overfeeding and limited treats. Beagles are great climbers. In his younger days, it was not uncommon to find 'Natty Boh' sitting at the kitchen counter eating someone's cereal out of the bowl. Do NOT turn your back on the little devils.
They can be escape artists. They can climb, dig, and squeeze - just when you think you have everything secure. I would never leave a beagle outside unattended, but then I wouldn't leave any dog outside unattended. Natty Boh has not been a problem. My previous beagle used to get out of the yard a lot - but that was back in the bad old 60s and 70s. He was a mostly outside dog. The good thing, though, is that beagles always follow their noses. In our case, it meant the beagle never got too far. He was always found in a very short period of time.
Younger beagles may be very active - some more than others. I have not found beagles to be so active, or require a ton of exercise. Natty Boh has a very nice off switch. Always has. (He just turned 4.) In true hound fashion, he sleeps 90% of the time. Sunny spots are best. He will hunt them down. Currently, he is sleeping on the couch. It is tiring work to be a hound.
Beagles are the class clowns. They will never cease to entertain you. Generally, they get along with all dogs. They are lovers, not fighters. Same sex, siblings, doesn't matter. Beagles are a true pack breed. The more the merrier.
They are often the choice of first time dog owners. They have a reputation for being an easy dog. (If there is such a thing.) I know many people who live in apartments and own beagles.
For a really good time, you want to work a beagles' nose. I believe the beagle sense of smell is in the top three of all breeds. It's amazing to watch. The nose misses nothing. We like to call them 'noses with legs.'
Does your little guy have a name? He's a cutie.
