Hi Jenny, Just talk to the rescue staff and explain your level of experience with dogs, what kind of lifestyle you have, and whether you are looking for a young or older dog and they will know the dogs they have in well enough to match you to either one or a few suitable dogs.
They may offer advice on training if necessary and will give advice on how to care for the dog, vaccinations required etc too.
Follow your heart and choose the dog the really 'speaks' to you, and take your time.
Visiting a shelter can be overwhelming as there are so many beautiful dogs in need of a new home, but don't make a decision on the same day as your visit unless you are 100% sure you have found 'the one'.
Take a short period of time at home to think after your visit and see if you still want the same dog the next morning when you wake up - it' a big decision.
You can never tell what you'll find in a rescue centre, but in general the quieter dogs IMO are: Whippets, greyhounds, older labradors, saluki's, older border terriers, older crosses, bassett hounds.
More on-the-go dogs (again IMO only) would be: Jack Russells, westies, collies, setters, spaniels, doberman, weinmeraner etc.
The pro's and cons are lengthy, and it will definitely be worth getting your dog insured to help with larger financial implications - There will be the initial adoption cost, vets fees for spaying/ neutering, vaccinations, food, bedding, toys, lead, collar, flea/ tick/ worm treatment etc, then make sure your insurance covers all large or long-term accidents/ illnesses.
Then there is the change to your daily routine, at least x2 walks a day, additional shopping for food, making sure the dog isn't left alone for long periods of time or whilst you are on holiday - do you have friends & Family whom would dog-sit?
Additional hoovering around house and paying to ensure the garden is secure if required.
It takes a lot of time to plan a day out if you are not taking your dog with you - it is safe, is there nothing dangerous lying about or in cupboards that it could chew through/ swallow etc - it's like having a toddler around, you have to watch out for things you wouldn't necessarily think of otherwise.
However - The Pro's FAR outweigh the cons! :-) Yippee! You'll have a new friend to take out and about and care for. You'll meet new people on your walks and explore places you never thought about going to also for wanders.
You'll always have an ear to listen should you need and they will love you if you love them back.
We got our dog 2 years ago and we simply couldn't imagine not having a dog around now - he has really made us a family, so I would recommend dog ownership to anyone!
But, take your time and find the right new member to your family.
All the best and let us know how it goes
