I'm one of those people who tend to believe that waiting until the dog is mostly done growing before altering is better.
I would talk to your vet of course and perhaps Bon's breeder to see what they say.
Readd all the info (both sides of the issue) and make a decision you can live with.
Is there no one who can maybe pet sit for you? Too bad I didn't live closer or I would. $20/day for all 3 dogs........LOL
