Luma could have an umbilical hernia. This is an opening in muscles wall located where the umbilical cord was previously attached. Typically these need to be corrected surgically and it can be done at the same time as when you get him neutered. It's never recommended to breed a dog who has had an umbilical hernia because there they are inherited. I would have Luma seen by a vet either tomorrow given this bump is large. The vet can diagnose if it is an umbilical hernia and can discuss when surgery should be done to fix it. I hope this helps!

    Hello. It does appear that Ace has a small umbilical hernia. Your veterinarian can examine him in person to discuss if surgery is necessary or recommended. In the meantime, monitor the hernia to make sure there is no significant change in its size or appearance. Thank you for using Petco Pet Education Center, formerly Petcoach.

    Yes, this looks like a small umbilical hernia. They are fairly common and are generally closed up when the animal is spayed or neutered. Usually it’s nothing to be overly concerned about, but certainly should be repaired at some point. If it gets larger then I’m more concerned and you should have it examined and get your veterinarian’s recommendation.

    This could be an umbilical hernia, the location would suggest that, umbilical hernias are common, it's basically a hole in the abdominal wall that requires surgical repair at some point, it is usually not urgent though.

My puppy has the bump in his belly and I don't know what to do! I'm just scared that she might have cancer and it might be malignant! Please help!!
You are right to be concerned - all new lumps and bumps should be evaluated thoroughly! It is a little difficult to tell from the photo, but this lump is in the location of her umbilicus, and it is suspicious for an umbilical hernia. It could also be some other type of a mass, but the only way to know for sure is to have it evaluated by your vet. Your vet can determine whether or not it is a hernia and/or take a needle sample to determine the type of cells. If it is a hernia, they can usually be routinely fixed during her spay procedure.

My pet got some bump r lump I do not know infront of his penis what to do ??
If i can see correctly from the picture, your dog seems to have an umbilical hernia, this is a quite common problem and this will need to be repaired surgically eventually, it's usually done at the same time as neutering (around the age of 5-6 months).

I just bought a puppy and he has a small bump where his umbilical would be. It's soft when laying down and I wanna know if it's gonna be a problem or what to do. He plays, eats, poops, and pees just fine.
The most common cause of a soft bump in this area is an umbilical hernia - this is quite common in young puppies, and in most cases does not cause any serious problems :) I would recommend having your vet check the when Thor goes for his first puppy exam and vaccinations, to make sure that this is what it is. If so, it can be easily fixed when Thor is neutered (if you are planning to have this done), or left alone as long as it is not causing any issues.

Hi my Silky terrier cross has lump in the belly top of his penis since one month ago. It’s little soft now. He seems fine and he eats and drink properly , but idk what is that ?
This looks like an umbilical hernia, quite common and usually not serious in dogs. It is usually recommended to repair it when general anesthetic is performed for castration. Anyway, generally speaking, this kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination (if it is an hernia physical examination will be enough). A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Other differentials include skin cysts, infections, benign or more sinister type of tumors (unlikely if Ichirou is under 5 years of age). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hi, Congratulation on the new addition to the family! so what I suspect from the description and also suspect from the pics I would say the puppy may have an umbilical hernia which is a common condition. I would suggest to take the puppy to first puppy check with a vet to confirm, the vet typically diagnoses umbilical hernias easily upon feeling the protrusion. In most cases the vet will follow up and monitor it till the hernia is corrected at the time of castration around 6 mo of age. Bear in mind that these hernias indicates a genetic predisposition to the condition that can be passed on through generations so the dog not meant for breeding anyway please have him castrated as soon as suggested by your vet.

My 7 week old puppy has a lump on his belly right beside his male parts.
This may be a hernia, which can occur in this area of the body (inguinal area). These are common in small puppies. I would recommend taking him in to your vet within the next couple of days to confirm this. Also you have the option of sharing a picture with either myself or another expert via consultation. Other possible causes for a lump is an inflammatory reaction (usually red), abscess (usually warm to the touch and may be painful, caused by trauma), or a seroma (blood filled sac due to trauma).

From the picture it looks to me like an umbilical hernia, which is a hole in the abdominal wall causing internal organs to pop through that hole under the skin, forming what looks like a lump. this is something that will need to be confirmed by your vet and if it is, surgery should be advised.

I have a 10 week old shih tzu puppy, we have noticed in the last few days a lump the size of a 20p coin on her belly. It is very soft but when you press on it it feels like underneath the lump there is a hole. It isn't painful when pressing it. Unabl
What you're describing could be a congenital inguinal hernia, which is relatively common in puppies and if needed is usually repaired during spay/neuter procedures. That said, with any new lump or bump, especially if it is growing in size, suddenly appearing, or bothersome, should be checked out by your vet in person to confirm what it is and what the best course of treatment may be.
