I am thinking about ordering a 6 pack which some would be kept for next year. How do I know what the date is on the product?

I looked everywhere on the individual package of the tubes and the box, there is nothing that mentions an expiration or use by date. There are phone numbers to call for questions...1-800-255-6826. Looking at how the tubes are packaged, my best guess would be that as long as they are sealed properly and not opened you could probably use unopened tubes at a later time. I have 2 dogs and ordered the six pack myself, if I don't use give my girls all 3 of their doses this year I will probably use it up next summer then.

What is the expiration date on this $41 product currently for sale???

The expiration date is usually stamped into the package. And $41 is very good price for k9 Advantix II. It's often quite more expensive from your vet or other sites.

Is this safe for sight hounds and/or dogs over the age of 12? Thank you for taking time to answer.

Yes, there should be no issue when using on a sight hound. I use this on my Brittney with no issues. Be advised this does not " repel" ticks. Ticks will still get onto your dog and can/will bite however, the tick will be impaired/ killed over a few hours time after biting. When used with a organic spray for Ticks you should have no issues. I have never had a flea on my dog nor my 2 cats. I recommend this product fully. Be sure to match your dog's weight with the correct Advantix.

Does it send all 6 doses at a time?

When you order a 6 pack that means 6 doses. IF you order a 3 or 4 pack. it is that many doses respectively.
