My gentle one year old wire haired dachshund keeps getting attacked by other dogs.  He is not agressive in any way and when I walk him and he loves other dogs and people, he even plays gently with the cat next door.
He has not been neutered and I would like to know if it is true that a dog that is not neutered poses a threat to other dogs? I hadn't planned to have him done but could this be the problem.
I am not sure what to do because it frightens me and I don't know how to stop this problem. 
Thank you for advice

Neutering is likely to cause more issues as they will want to mount him instead, (potentially more dangerous for him), some male dogs will attack any male regardless if neutered or entire anyway.

At one year his testosterone levels will be high and dominant males will want to put the young pretender in his place.

The levels will drop down to base levels once puberty is finished.

Vigilance is the key only allow him to play with bitches and males known to be friendly with other males and avoid strange or dog aggressive males.

This will keep him safe and just as importantly stop him from becoming male aggressive/fear aggressive himself.

Can you exercise him in a place with less dogs until he is around 20 month to 2 years?

Actually entire males are perhaps more likely to pick on neutered males, mainly because they can't figure out exactly what they are.   Could be an entire dog poses a threat to other entire males, but that's normally only if the body language suggests this might be the case.  Most entire dogs won't react unless challenged.   We kept entire males together with rarely anything more than the occasional scrap over something.   We did have a youngster who started challenging his uncle when he reached around 18 months, to the point we had to find a home for him.

Best I can offer is you protect your Dachsie knowing some thing about him winds up other males.   He doesn't really NEED to be playing with out dogs, and especially if he produces this reaction.

Having neutered a rather sensitive boy at around two, I'd never do it again unless for medical reasons.
Did it after advice from vet (good money earner) & breeder (???), within six months all his previous friends wanted nothing to do with him apart from hump him & he became very nervous after continually being charged by strange dogs coming out of nowhere.

Crikey Lacy I am so sorry to read that about your boy.  These vets really need to stop thinking about lining their pockets and more about the best interest of the animal in their care.  Our vet is new and told me straight away that our dog should be neutered and that there is a high risk of cancer developing after the age of 5 in the prostate etc.  I know this but I understand the risk is minimal at around one percent.  I am sorry this happened to your dog and thank you for sharing with me.

Actually Prostate Cancer is more likely in NEUTERED males. http://www.naiaonline.org/pdfs/LongTermHealthEffectsOfSpayNeuterInDogs.pdf
On the negative side, neutering male dogs 
• if done before 1 year of age, significantly increases the risk of osteosarcoma (bone cancer); this is
a common cancer in medium/large and larger breeds with a poor prognosis.  
• increases the risk of cardiac hemangiosarcoma by a factor of 1.6
• triples the risk of hypothyroidism
• increases the risk of progressive geriatric cognitive impairment
• triples the risk of obesity, a common health problem in dogs with many associated health problems
• quadruples the small risk (<0.6%) of prostate cancer 
• doubles the small risk (<1%) of urinary tract cancers  
• increases the risk of orthopedic disorders
• increases the risk of adverse reactions to vaccinations

hope your dashound will be ok poor chap
my late grandmother had wirehaired dashound they are lovely one of them use to go for people if they went near me in my pram
best wishes to your little chap

Wish  I had got all those statistics to hand yesterday when I was trying to explain to someone why early neutering is not advisable  in most cases

Stephanie Presdee says:  I would learn about other dogs body language so you can anticipate, and take your dog in the car out of your area , somewhere without lots of other unruly dogs off leads.parks and the streets near you may not be the best place to walk him.
