black labrador retriever experts?

Buy a choker chain and take an obedience class and all will be clear and you will understand. Then you will be able to train any dog in the years to come.

Okay well i'll start by saying i am not a Black Lab expert. But have had dogs all my life and very involved in the dog world through training and showing and breeding etc.
And we would never let someone have 2 litter siblings because you find that they bond with each other rather than you no matter how much work you put in. Also be carefull where you get them from if you are getting puppies because they have got into the puppy farm market and you don't want a dog with on going health issues, temperment problems, the list goes on. If you are getting a puppy go on the breedtemperamentite and speak to someone on the comittee they'll point you in the right direction and give you all the imformation you will ever need because at the end of the day you want a happy healthy puppy from the right background bred for love not money. If you are going to rescue also speak to someone on the club comittee and rescue dogs. Because not many people know that nearly every breed has a rescue section specially for the breed. And trust me they will always be happy to help. And with your training make sure it is positive as a dog trainer myself i do not agree with choke chains or any other negative training. Find a good training club near you and never do anything that might make you dog scared of you, the relationship between you and your dog should not work through fear but through willingness and happiness. Good luck.
And by the sounds of it, it will be a brillant home.
Sorry for it been so long, but i hope it's helped you

Labradors are prone to hip/hind leg problems.

Insurance! If you don't know how to 'punish' a dog then I don't think you're ready for one!

I advise you to add a dog version of a first aid kit to that list. Just in case, and insurance. RSPCA./ASPCA sites are a good place to start to find a dog, but you could always take a trip around local dog shelters too. Also, get the It's Me or The Dog books by Victoria Stilwell (or ones by Cesar Millan if you are in the USA) Mostly health problems are from being overweight, old age (back legs failing) and LUNGWORM (when your dog eats a slug or a snail it can cause lungworm- vets immediately in this case) If you read Victoria Stilwell/Cesar Millans books it teaches you the basics like heelwork (walking with you) and dog physology. You can watch Dog Borstal, It's Me or The Dog, Cesar Millans show (can't remember its name!) for advice on training and what you should do.
Although you obviously want to love the pups you are going to have, remember they shouldn't be babied or spoilt. NEVER feed them human food (scraps are exceptable on the odd occasion- that sometimes cannot be avoided!) or milk/chocolate. They shouldn't jump on people, as they will get big dogs being Lab Retrievers! When you take your pup(s) home for the first time, give them an old tshirt of yours each and a ticking alarm clock wrapped in the tshirt (this gets them used to your scent and the ticking is like their mums heartbeat)
If you are getting two pups, it might be easier to take littermates yes- they are not strangers to each other and will settle in faster!
Sorry for the long answer, and congrats on the new pups!

1) If you are feeding a quality food, you do not NEED vitamins & you can actually do more harm than good, by causing a puppy to grow too quickly by over supplimentation.

2) If you enroll in an obedience (puppy kindergarten) class, you will learn how to correct the dog, but I suggest saying "NO!" or "AAAaaant"! if they do something wrong. Often, you need to remove something from their mouth or re-direct them.

3) Please, please do NOT get two puppies, at the same time! It will be difficult, if not impossible to separate them if they live in the same environment. And what you didn't even mention and I consider the most lethal reason not to get two at once, is that they will BOND to each OTHER, not to you. (Their bond to you will be much less, than if gotten with time in between them.) They will be difficult if not impossible to separate (ever, for any reason) and it will be very hard to train each puppy.

Now, if you are determined to save two dogs, why not just wait 6 months or one year, and go get a second dog, after the first is crate-trained, housebroken & obedience trained? Having a well-trained dog will help the new one pattern-off good behaviors and will make your life easier.

If you are compelled to save two dogs, then look for two adults who cannot be separated. Rescue groups do get two dogs in, who have lived their lives together for 3-5 years and need to stay together. Two-somes of this type are hard to find homes for. Hopefully, they will already be house-broken & crate-trained. Trained adults are much easier in multiples, than untrained puppies.

Quote: …"the reason i want two dogs is that i can save the life of two dogs, whether it's form a breeder or adopted from a shelter!"

BITE YOUR TONGUE. You will not be "saving the life" of any puppy who has a reputable breeder. Reputably bred puppies aren't produced, unless they have homes for them & they will keep them as long as needed, until they do find the RIGHT home. Reputable breeders will NOT sell yor two puppies, period - they KNOW better.

Homeless dogs & mixed-bred accidental litters, in shelters or rescue groups, come along every few minutes. You can save two (or more) by simply doing it right, one-dog at a time!

Make sure you're feeding a decent dog food to help prevent future hip problems, which are common in Labradors. I highly recommend Orijen, puppy or all life stages formulas - or Acana's grain free formulas. Obedience and basic training classes are a MUST. I would invest in pet insurance just in case you ever have any problems, also buy or organize your own dog first aid kit (You can find information regarding these online). I would not be worried about vitamins - with the right dog food, your dog should have all it needs nutritionally. If anything, you can add kelp powder and salmon oil to the diet. A container to store dog food, so it doesn't go stale in the bag. Puppy pads/papers to help house train. Remember, never shove your dog's nose in their accidents - that is the wrong thing to do. I actually, suggest getting a Lab puppy now - enrolling in obedience/socialization classed - then once that pup is six months to a year old and you have full control over that pup, get the second puppy. This will be much easier to train, and there won't be too much of an age difference in the two.

If you have any other questions, feel free to ask.
