I agree with everything My Fair Lacy said.
By neutering him now, you will not have to deal with the undesirable traits unneutered male dogs often start liking marking indoors. Once they start, often neutering doesn't stop it.
He will also be much more pleasant to live with. If there is a female in heat nearby he will whine and carry on, plus you will always have to worry about him getting out. A male determined to get at a female can become an escape artist.
He will be a much healthier, happier pet if you get him neutered. |
