We have 2 senior dogs Mizzy and Beth
Mizzy is 15 yrs old he's always been snappy with strangers (never with us) he's slightly deaf/blind arthritus all round, flea alergies etc but he still soulders on.
Beth is 10 nearly 11 and she still act's like a puppy, only after very very long walks she will get lame but hardly ever, she really good for her age considering never been walked past the age of 2 till now crap food/water never had vaccines/vet check ups was very over wieght etc i think she will live to a very good age
