My parents will not neuter my chihuahua?
if cost is possibly the issue, call your local animal shelter or humane society to see if they can direct you to a low cost neuter clinic. some shelters even offer the service cheap or free. call around and see what you can find out. maybe remind your parents that smaller dogs like that will be able to easier mark around the house and you won’t find it until it is too late and stinky. once it starts it is very hard to break them of it. since you seem to be aware of all the potential health issues, i won’t even go in to all that.
