A,re there things u can do at home to improve pup's umbilical hernia to close without surgery?

The pup in 7 weeks old, a female Weimaraner

Take your backyard bred dog back to the breeder. It is too young to be away from it's mother and littermates. The dog's hernia needs to be repaired. That is, unless it has a large opening. In this case, the vet can give you a truss. You don't ever try to repair a hernia yourself. Only a vet should do this. You could end up killing your dog.

Nope

You know thread? That you sow with? Use that, tie it around it and wrap it around a few times.. That's what pet hospitals do

Why would you have a 7 week old Weim? 8 weeks is the minimum age to sell pet dogs, and in some areas, it's actually illegal to sell them this young. On top of that, umbilical hernias are often inherited. What other problems has this dog inherited? No, there is nothing you can do to close the hernia at home. You should have your first vet visit with the puppy immediately, so you can ask what you can do at home to help it. If it's serious, then t he vet will have to act now on it. Otherwise, they can usually wait until spaying and will be closed then.

No their is nothing you can do, my Maramma has the same problem. I have asked the vet and it seems like these things happen to some dogs. They said so long as it didnt grow substantially bigger then everything is AOK

It depends on how large the hernia is. Some cannot close on their own, without surgery. Has a vet examined your puppy? S/he would be the best person to advise you, on your options/treatment. WHY did you accept a female dog with this anomaly? I hope you were not planning to breed it - this can be genetically caused & the pup should NOT be bred. IMO -if reputable, the breeder should have had it fixed, before selling her or should have heavily discounted the purchase price. Seven weeks is an illegal age to release a puppy for sale - in many states. There are puppy LEMON LAWS against it. (Another RED FLAG about who you got her from.) Sigh!!!!!!
