@USER123456,
Did the breeder give you certification of the puppy's shot and deworming? Even if the breeder gave you the certifications, you still need to make an appt. for the vet to check out your puppy. I hope you have a vet in your area that's not affiliated with those huge nationwide chains...private practice vets are usually more affordable and much less likely to order unnecessary tests or overcharge on medications. We have been very fortunate with out local vet and he's taken very good care of three cats (until cat heaven) two beloved springer spaniels and three vizslas. We only have Ruby right now.
Where do you live, are you near Maryland? I ask because I may be able to find a support group near you that you can reach quickly if you have questions. I'm more than happy to help out with the new puppy, I just am not always online and would like you to have a network of folks who can also support you and the puppy.
You can always send me a PM if you have a question you don't want to post in public.
If it helps, I have to tell you that listening to howling puppies is close to torture...especially when you are sleep deprived and anxious for quiet rest....but it doesn't last very long....just stay consistent with the crate training......at least until he is potty trained.
I really just want to help, so if I tell you something you already know please don't think I'm treating you like a dope...I'm just not sure what kind of help you need so I'm trying to cover all bases.
Did the breeder tell you what food to buy and how often to feed the puppy? He needs three small meals a day for awhile, and I have to check with some folks because I've forgotten exactly how long you keep them on three before you only feed them twice a day. I really recommend feeding the dog twice a day, because larger beds like labs can develop bloat if they eat too much at one time.
