I too know of puppy mill stories in Germany. None of them turned out well. If this is your first puppy ... I beg you to do a lot of research first. All breeds are very different and not all of them are good for families with young children. Have you considered the cost of having a puppy/dog in your family? Veterinary care and food are very expensive. Especially if you feed a good quality food. And when you move, the cost of moving your pet falls on you. If the weather is not favorable the time of year
that you move ... you could end up boarding your pet for several months ... VERY expensive.
The reason (I hope) that people charge so much for pups is that it costs them a lot to vaccinate pups and care for the mother. They also want to make sure that they are finding homes that can afford the cost of keeping a family pet forever. The price may look big .. but in the long run may save you a fortune.
You should know the breeds you are interested in. Then you should be able to see the mother and father (dogs) and have a chance to see their temperaments. A responsible breeder can make these arrangements. You should see veterinary records for the care of the mother and any genetic testing that is recquired to breed or sell that particular breed. Ex. - Labradors and other large breeds have genetic screenings for hip and elbow dysplasia.
You might be thinking ... "I am not looking for a show dog!" It still is best to see the way the parent dogs interact with you and children.
I have raised puppies. I have adopted strays. I love them all and they all deserve a chance for a great life. If you have no experience with a dog in your house, please find a responsible breeder that will help you learn about caring for your dog and integrating them fully into your family. There is a LOT of training involved with a dog, especially with children in the house. If your husband goes away a lot ... imagine having an infant that does not wear diapers and has razor sharp teeth (they don't have flexible fingers to play with and use their mouths ...). It can be VERY stressful if you are not prepared.
Maybe you can find a local pet lover to help you prepare your family and home and to go on the puppy search with you. The first cute puppy you see, you will want. If you have an experienced person along that is not so emotional about the search, it might help you. Then again, a lot can be said for "that feeling" you get when you first lay eyes on them!
Perhaps you can ask at the veterinary clinic. They may have a pregnant patient to tell you about. Or can make recommendations about local experiences. You also need to find out what German vets speak great English in your area. Then you will know where to go when you can't get in at the US Vet clinic. Even if you speak German ... the medical lingo can be confusing, especially when you are stressed with a sick pet.
I know that I did not answer your question. I just know of too many families that brought a puppy or kitten home before they were truly ready. It is the pet and the children that suffer most. If I can help prevent that ... I take every opportunity. Please be prepared so that it goes well for your family and the puppy!!
Good luck and enjoy your future puppy snuggles.
