There may be nothing wrong with him; the testes are a very tender part of the body and he may have just had a knock or a bang and is feeling a little tender. If the swelling and the redness does not go away after a few hours, then you should take him to the vet to be checked over, just to make sure that there is nothing serious going on.
Unless you want your dog for breeding (and that is a decision that should not be taken lightly because there are far too many unwanted dogs in the world as it is, and though you may be a responsible owner, you cannot possibly account for the people who would have responsibility for the pups), then you should seriously considered having your dog neutered. In male dogs, this means castration, and though it sounds a terrible thing, you could be doing your dog some very real favors.
It has been estimated that two dogs and their offspring can produce 67,000 pups in just six years, which is a scary thought. In the United States, it is thought that 50% of dogs will not leave to see their second birthday simply because there are too many of them and not enough people to give them homes.
Having a dog castrated means that he will also avoid some potential health issues such as testicular cancer. Castration can also make dogs less aggressive because they are not being fuelled with testosterone. Obviously, not all male dogs are aggressive, so this is something you will have to think about based upon your own dog.
Castrated dogs are also less likely to run away from home because they have no interest in finding a bitch that is in season.
I think your dog is suffering from Orchitis, Orchitis or inflammation of the dog testicles is the result of injuries (barbwire pricks, nails, incisive injuries, small wounds, etc.) in which microorganisms enter. It can also happen during the course of some specific diseases like influenza, distemper, mumps, etc. "Hydrocele" is a disorder in which serous fluid accumulates in the scrotum. "Testicular Torsion", however strange, can present itself suddenly. The dog experiments a sudden pain and refuses to make any movement. His march is rigid and abnormal, showing a lack of appetite and, sometimes, vomiting. When the afflictions affect only one testicle, the scrotum is swollen and with an excessive accumulation of fluid and in pain. On occasions, it is accompanied with lethargy, dysuria and abdominal pain. When orchitis is president along with epididymitis, as a consequence of traumas or hematogenic dissemination of infections from other points of the organism, the dog starts walking rigidly and gets a strong pain in the scrotum and testicles. The formation of tumors, be it in the testicles or scrotum, are relatively frequent, especially in dogs of old age although it also happens in middle-aged adult dogs.
The tumors that affect the testicles are usually malign, but the ones that affect the scrotum are generally fibrous or wart-like. The atrophy that affects testicles can be due to many causes: The final stage of an orchitis, general advanced avitaminosis (any of several diseases caused by deficiency of one or more vitamins), malnutrition, cachexia (any general reduction in vitality and strength of body and mind resulting from a debilitating chronic disease), etc. Any time you observe anything abnormal with the genitals of an animal, you must urgently go to the vet.
There are a number of reasons your dog's testicles could be swollen. Trauma or self-mutilation are possible. Testicular infections, cancer or torsion is possible. Brucellosis is an infection disease that can cause testicular abnormalities.
Have your dog examined by a veterinarian to determine the cause of the swelling and redness. The sooner a diagnosis is found the sooner treatment can begin. This condition sounds very painful and your veterinarian can help relieve your dog's discomfort.
I have a one year old pit and his testis are red and swollen also, thats because when the itch, thy use their teeth to to nible on them. Or it might be from bug bites...I'm goin to take him to the vet asap to be safe and you should too.
It may be something like a fluid build up, also known as Hydrocele. If it lasts more than 24 hours I would definately get him in to see the doctor!
I guess it might also be important to ask if you just recently got him and maybe aren't sure what they should look like? Has he been licking them excessively? Has he recently been to the groomer? Dragging his butt a lot? Only a vet can say what's wrong really and they probably need to see him. I'd give them a call at least (though they probably will need to see him as it is usually too difficult to come to a diagnosis without an examination). How old is your dog? Does it seem painful (not really a qualifier for treatment)? Swelling should always be examined as soon as possible. Have they actually changed in color and you've noticed they are more red (it can vary from dog to dog)? It could be an injury, an infection, tumor/cancer, prostate cancer or any number of things. Your dog may need to be neutered or he may just need some antibiotics and some special care :-). It may be nothing and normal. It can sometime indicate a problem elsewhere as well. I'd say if you are concerned I'd check. I'm a girl and the thought makes ME uncomfortable :-). I don't know if posting pics on here would be considered appropriate considering the subject. Please let us know what happens.
Don't know if this helps, as I a not really knowledgeable about canine disease, but my 5 year old boxer recently became lethargic and feverish. After a day of noticeable pain, he showed difficulty sitting and I noticed that his testicle was swollen to about three times its normal size. After a vet visit, the diagnoses were: 1) Scrotal dermatitis - if accompanied with peeling of the skin, as when sunburned, 2) epidymitis (sp?) - local infection of testes, 3) testicular torsion, 4) tumor - not usually presented with skin peeling. I was given a steroidal pain med and antibiotic, with the suggestion to neuter after swelling had decreased by half. Elevated temp. Seems to indicate infection, so although allergic reaction is possible, there are other problems with similar symptoms. Hope this helped, good luck.
My dogs is about 20 weeks old he is a jack russel cross with a border terrier and he is eating fine he is in no pain but is very sleep and likes to dose of every now and again we only noticed a big swollen patch on his right testicle it has changed colour to a dark purple/ black colour and I am very worried should I be?
His testicles are very red, swollen and hard. He is starting to urinate everywhere. He is very thirsty all the time. He is very quiet. He still has a very good appetite. I am worried.
If he's not neutered it could be testicular cancer. I would have him checked by the vet. I hope it all works out.
My dog is nearly 11 years old he has a very swollen scrotum and is not eating or drinking he is due to see the vet on monday any ideas is it cancer
Your dog needs to be examined by a veterinarian. There are several things that can cause a swollen scrotum. A mass on the testicle (may be benign or malignant), testicular torsion, testicular infection/abscess, testicular cyst, trauma, or allergic reaction (bug bite or dermal hypersensitivity) are all possible. Your veterinarian may want to do a fine needle aspirate or the testicle or an ultrasound depending upon examination findings. The treatment will most likely include neutering.
Well it is probably just bumps my dog has them to.
Hes probably licking them too much... Careful if some dogs really won't want them they can self-mutilate, and you don't want that...
Take him to the vet. Don't try to treat that at home.
