Millie is on Heat

[harm_less]

Right , much has been assumed , sure not much to do with female dogs , always owned males in past , not money motivated , more interested inhte progeny , will keep one hopefully ..Not a first litter , has had 2 in the past .
I also checked with vet , being a dog of small stature , will be better than a larger lab  or GS with a shorter life span .
Hopefully this allays some fears

No assumptions. Simply giving my point of view. Dogs are bred and inbred, for the purposes of selling, or using them as fighting dogs, or other nasty reasons.

No matter the size of the dog, the age thing is more important imo.

Think of the dog. It's 8 years old fgs. It has no choice, but you do. Get a younger dog, if you want to become interested in the 'progeny' of it's offspring, and descendants.

So no, your words don't allay any fears for me.

Just my two cents worth.

What Muzza3's vet was referring to was the potential lifespan of the breed. Large dogs are short lived whereas a Jack Russel is likely to get to its late teens. On that basis an 8 YO JR is the equivalent of a human women of 40YO considering pregnancy but 8 years is near geriatric for a larger breed dog.
