We should've gotten our dog's neutered. But one obstacle is the vet bill, & my dad's work schedule.
One thing for sure is intact Male dogs pee more, & we deal with constant peeing in the house. Hard to keep up. They were house broken, but then our irresponsible big brother decided it would be a good idea to leave the house for along time, while we were gone caring for the birds.
The dogs took a reverse course, & left us constantly cleaning up pee.
Also, my dad's dog is a crypt-orchid, developed abit of a perineal hernia(Not Severe), & has a type of tumor growing under his skin in certain areas.
Everything that I've learned said unfixed animals are more susceptible to cancer.
About the vet bill being an obstacle. Sister's kitten got fixed at a place that does low cost spay, & neuter. The spay was $35, plus tax, Anesthesia, IV, ect they charged us for everything else. My sister spent over $500 for a low cost spay.
