Theo 5-year-old male black Lab mix 99 lbs Neutered

Background: Theo joined our program in May 2022 from the Stockton shelter where he’d been picked up as a stray. He was found to be heartworm positive once he was in our care, and his initial foster in Alamo nursed him all the way through his heartworm treatment protocol. He completed the two final treatments to rid him of the heartworms last August. The fosters grew very fond of Theo during his stay with them and had hoped to adopt him, but he nipped their kids – and they just could not trust him with children. So we’ve relocated Theo to Diesel Ranch in Placerville as he looks for his forever home.

Recent Interview with Theo:

Q: How do you usually spend your days?
Theo: “I am a dog of relaxation. Two 30-minute leash walks per day is plenty for me. I do kinda alternate between lying on my dog beds and chewing on them. Hah, they said those Orvis beds were indestructible – I proved them so wrong.”

Q: You’ve been called a bull-in-a-china-shop kind of dog. Can you comment on that?
Theo: “Well, I like to be first in line – for everything… for food, for a frozen marrow bone, for a belly scratch, for an ear rub. And if I have to push my way through the crowd to get these things, then so be it. After all, it is all about me.”

Q: What is your opinion of intact male dogs and dogs that come up and stick their head in your face?
Theo: “Stupid question. Stupid intact dogs. Stupid dogs. I don’t like them. I do not want them in my face, in my life. Keep them away from me and we’ll be just fine.”

Q: I understand you practice yoga. What is your favorite position?
Theo: “I prefer Downward Facing Sofa but Warrior II While Gnawing Bone is a close second. I do my best yoga poses on my couch, yeah, MY couch. Gosh, I can meditate on it for hours.”

Q: So why does your foster call you “Butthead” at times?
Theo: “I personally think that is unfair, but I do have a tendency to gather towels and blankets and shoes… I am a collector of sorts… and then chew on them a bit. He has also called me Theo The Destroyer – now that is just plain wrong!”

Q: What’s up with this drooling when dinner is headed your way?
Theo: “A genetic aberration, I guess. I attribute it to my Grandpa Klaus who was mostly Saint Bernard. Now that guy could drool!”

Q: What would be an ideal adopter for you?
Theo: “A retired guy that hangs around his garage and builds things… and just wants a dog hanging out with him, chasing rats and stuff. A guy that works out in his yard a lot and needs someone to dig up gophers. A guy with a few cool friends that I can meet and become friends with. Yeah, that would be a real good match for me. That guy is out there.”

What Theo's Initial Foster Says:Theo is a very big, handsome and strong guy. He is a lover of his family and just wants to be around you all day. He will follow you all day long. He constantly looks for pets and for you to hold his paw. He really makes a great companion. Theo does not realize his size and strength and could use some work in learning manners and leash skills. We are working very hard with “sit” and “stay” before entering and exiting outside. Theo has a soft mouth when taking treats. Theo is house-trained and crate-trained but prefers not to be in a crate. He knows basic commands of “sit”, “paw”, “stay” and “out”. Theo can be left alone inside for a few hours but does not like to be left outside alone for long periods of time. He can tend to get anxious and starts to lick at his front right paw. Theo sleeps quietly through the night on his dog bed in our room and has access to the entire house, but really you will find him in the room where you are. Theo also loves to play fetch and go for walks. Theo can be protective of his owners and has reacted by lunging, barking and growling to people and dogs. For this reason, he would do best in an adult-only home and be the only dog. We did a DNA analysis of Theo and found that he was a mix of Doberman, Rottweiler, St Bernard, Labrador retriever, and a few other breeds.

What Theo's Rescue Rep Says: What a great knucklehead dog – except for his occasional snarkiness. Best for Theo to go to a home without children. He is a bit of an ongoing project, but the payoff will be huge. Leash walks are great for Theo – he loves them. Slow introductions to new people work great… and he quickly becomes comfortable with new folks. Could be fine in a home with another dog. Not good for a home with cats.

Medical: Theo is fully vaccinated, microchipped, neutered. Part of his tail had to be removed due to severe case of “happy tail” that refused to heal – so he now has half-a-tail. He has pulmonary hypertension – possible an effect of the heartworm – and is on a daily Sildenafil med for that. We are endeavoring to resolve a long-standing hot spot on Theo’s front right foot that he often licks.

Located in: Placerville

Our volunteers donate their personal time phones so please only call during reasonable hours (8am - 8pm). The Rescue Rep identified in the dog posting is the only person with information about the dog - please only contact the designated volunteer. We do call everyone back within 2-3 days so please be patient. We work very hard to make the right matches for the dogs and for the new owners. We get 3-5 dogs per week; we do not have a facility where the dogs are housed, they are in foster homes throughout the Bay Area.
