Beagles are very definitely not first-time dogs. They are wilful and stubborn, and need owners who know what they are doing, and know how to work with their hunting drive. Inexperienced owners and/or not enough training would be a total disaster - they are very prone to roaming
THIS ^ Beagles are lovely dogs, but very hard work, incredibly energetic and with a very, very strong prey drive (re: their energy levels - they are described as a dog which can run at full pelt all day while yodelling - and this isn't much of an exaggeration). They are also hard to train, wilful and disobedient (but are usually very sweet-natured).
They are short-coated, so easy to keep clean, but shed a lot - you will find little spikes hairs like hedgehog prickles in the weave of your jumpers, carpets etc. They are also greedy, thieving, little buggers, so you will have to watch them for food left lying about.
Wastes are just wonderful! We've had four - yes, they are stubborn sometimes, but they are bright, intelligent, charming, full of fun and just the BEST! (You may notice a slight bias in my opinion . . .
).
All of ours have been fabulous with children of all ages, ad very trustworthy with our cats. They do tend to be happy - but that's terriers for you - and require a clip every two/three months and thorough grooming daily and after every walk. If you clip your dog yourself, make sure you clear a "landing strip" under his/her tail - necessary with any long-haired dog. They have a double coat, so will get very tangled if you don't groom them properly, but they shed very little hair. They aren't usually greedy, but are interested enough in treats to train with them. They are also nice and portable if you ever need to carry them anywhere (e.g. escalators).
They are the BEST!!!
