Two dogs generally equal more work...two to bathe...two to groom...two to feed. But the benefits outweigh the perceived disadvantages.
For one thing, bathing two is not too much harder than bathing one. Throw both of them in the tub and you're done in 10 minutes. Feeding? Two don't eat much more than one, especially these little guys. Grooming? So it takes 30 minutes instead of 15 minutes.
Our oldest was depressed before Rocki came along. I didn't realize it at the time...how could you? But after we got Rocki, Bruiser realized he had a purpose. He took it upon himself to treat Rocki like his own child...he taught him the rules of the house through body language, growls and barks. Rocki is always clean...Bruiser "washes" his eyes, ears and face every night and Rocki has learned the routine and reciprocates with his brother. I no longer have to purchase expensive products to clean the dirt from their eyes because they look after each other. After their outdoor bathroom break? Again, they clean each other off, thanks to Bruiser for teaching this to the little one.
Play time? It's fun time now that they have a live body to chase toys with, jump on couches with, and generally run amok with. I don't have to worry as much about them getting exercise because they exercise each other. When one is too dragged out, one will motive the other to run through the house and up and down the stairs, through the living room and round and round the tables until each of them collapes from exhaustion.
Psychologically they are such happy little guys because they have a companion just like them to chum around with. When company comes...sure, there's a bit of competition for attention...but in the end they are buddies through and through and share the pats, the hugs and kisses.
When I first suggested getting a companion for Bruiser, my husband looked at me like I had grown horns. After I brought Rocki home, he admitted that it was the best thing we could have done.
