Cooper is 5 months now. He was born January 22 and we got him from the HSMO last March 31st. I thought he would be my dog to replace my first Rottie that died but though I train him, I do not think DH can live without him now...
Lucy was 3 (at best estimate).
Koda was 9 weeks.
Our cat was 3 months.
Next dog (and cat) will be 6 months plus. No more babies in this house! Adults are more predictable and easier to train.
