I love british bulldogs - and certainly some rotties - not all - there seems to be 2 sorts. the ones that like me and the ones that scare the hell out of me.
My friend runs a rescue - Halfway Home at newark - she loves rotties and gets a fair few in - give her a call when you are ready.
I know she has Zoe in -
I also have a link on my site to the bulldog rescue -
and you can contact them about them. However, bulldogs usually go into rescue cos people dump them for a reason - like i say - i love em to bits - but they are unique.
Also - and its entirely up to you - i think that the 2 dogs you have chosen are entirely different. One will want bags of exercise - toys, playing - energy - attention - meet the rottie - and the other - odds are just wants to potter about the garden, be pampered, brushed, meet the folks - and the odd jaunt in the park.
why not write down a list of what characteristics you both like in a dog, and what you don't want - then just look from there.
Thanks Lotti for suggesting my Baby Bear - he is a dream isn't he? However, i would say that he is s real mix bag of things in there - but mostly i think he has a nice collie temprament - which probably wouldn't do. His right mom and dad are waiting there somewhere for him tho.
