OMG @Jynx Yes they are similar. We got Cindy, as my cat Reggie had to be put down due to having a cancerous lump which made it very hard for her to eat. And she looks just  like Razz.

I am not sure what sorry of dog I would get. It would depend on the yard size. As a child we always had samoyeds and if I got a big dog, my choice would be either a Husky or German Shepherd. 

And yes Jack Russell's are definitely a high energy dog. They used to be a hunting dog. But they are also very clever and Russell was a great companion dog for me.

Thank you for you condolences. Losing a pet is just like loosing a family member in my book. 

When I was married we had the 2 Jack Russell's and a Jack Russell x Shitzu as well as the cat. And they all wanted to spend time with me and not the husband. 

I have a photo of me lying on the lounge with all 3 dogs lying on some body part and the cat was laying across the back of the lounge. Lol
