im going to re0iterate the point that dogs dont live forever...and since your only in your EARLY 60's its HIGHLY likley YOU are going to outlive your dog.
the chihuahua has the longest average lifespan and can get into its 20's (however mid-late teens are more likely)
so even the breed with the longest lifespan could be easily outlived by a human...
lets see, lets say you whent with a chihuahua, simply because they live the longest on average of all breeds...now lets say that chihuahua lived to a ripe old age of 18...thats OLD for a chihuahua (14 is about average)
that would make you ONLY 80 yrs of age...remember, humans can live untill there in their hundereds!
if the loss of another dog is going to be so hard on you that you MUST outlive your dog you might want to reconsider...
unless youve been told "well mr smith, you have cancer and have 6 months to live" you have absolutly no idea if your going to live till your 90 or get hit by a bus tomorrow...
so you HAVE to keep in mind that there is a very strong possibility you WILL outlive your dog.
now, what if on the off chance your dog outlives you...lets say you have abad heart or something...
are you SURE you have a home lined up.
your ex wife loved your last dog, mabe she wont like the new one? what if she passes before you, are there other people in your life you can absolutly rely on to take ANY dog you end up getting, even if its not "their kind of dog"
i know if i were to die today my mother would take my chihuahuas, and a frined form another forum would be taking my cresties because my mum and dad dont realy "like" the cresties...theyd be looked after but not realy LOVED the way they should be.
having these plans in place are just as important as having a will.
im also going to ask, instead of making lots of new threads about the same subject that you put additional info under the same subject heading so theres not 3 different threads about the exact same thing
