File #25-085 Current Foster Location: Renfrew, ON *Please note that we do not typically adopt outside of a 2 hour radius from the foster dogs current location* Hi, I'm Inara - Your New McDreamy if he was a she. Guess what? I'm finally learning to be the big goofy puppy I was always meant to be! My journey has been more dramatic than a season finale of Grey's Anatomy. Born with Entropia in both eyes (which was basically my version of being stuck in an elevator with my ex), I was in serious pain until the amazing Dr. Julie (who's totally giving Dr. Bailey vibes) gave me relief. Before my eye treatment, I was basically Meredith Grey in the early seasons - dark and twisty, walking around with my eyes closed because opening them hurt more than watching McDreamy's death scene. I relied on my doggy friends and my nose to navigate life. But now? I can see! It's like I've been upgraded from intern to attending overnight! I LOVE following other dogs, playing with toys, and prancing around on my hilariously oversized paws - I've got the coordination of George O'Malley on his first day in the OR! To continue building my confidence, I'll need another canine brother or sister. House training is a work in progress - the outside world is scarier than the hospital basement, but I use pee pads when needed. My crate used to terrify me more than a code blue, but now we're cool. Car rides make me nervous but with time I'll improve! Oh, and heads up - I'm definitely a couch potato who believes your furniture is our furniture. Consider me the Christina Yang of comfort - "I'm not leaving this couch. It's my person." That is, unless YOU want to be my person? So, what do you saypick me, choose me, love me? Please visit our website www.ittakesavillagedogrescue.com to learn more about this amazing dog and to see other available dogs.

Baloo is one of 11 siblings born on Family Day. He is a typical little puppy.....eat,.play, poop .sleep (maybe not in that order!). He's active and playful and loves cuddles. He looks just like his momma, Mastiff/German Shepherd and still has lots of growing to do, so some experience with the breeds will be beneficial.

**IF THIS LISTING IS STILL POSTED THIS DOG IS STILL AVAILABLE FOR ADOPTION. NO NEED TO EMAIL ASKING IF THE DOG IS AVAILABLE. PLEASE READ THROUGH THIS BIO THOROUGHLY AS INFORMATION ON HOW TO APPLY IS CONTAINED IN THIS LISTING** For Adoption: Titan! Please read our dog bios carefully to be sure that the dog you are applying for suits your family and lifestyle. We at PDR believe in the benefits of post-adoption training for our dogs and their families. This allows for continued socialization, learning and helps to create a well-mannered and balanced dog. Post-adoption training is a requirement in our adoption process. To apply for adoption and for more information on our process and requirements, visit our website at https://pounddog.ca/adoption-info/. Take a seat while I tell you all about Titan who is a certified 10/10 good boy! Titan is approximately 4.5 months old and he is a perfect mix of Bullmastiff and German Shepherd, with I’m sure a bit of Husky in there too. Titan is currently a whopping 32lbs, he is growing fast now that he is on a good consistent diet and he is gaining weight quickly. Titan will grow to be a very large and sturdy dog and I expect him to exceed 80lbs fully grown. Titan has a beautiful tan coloured coat that is so soft and luxurious, he’s got some black markings coming in along his back, and a beautiful black mask. He really is a very striking and good looking dog. He has the most heartwarming brown eyes that will watch every move you make, and he is always looking to you for direction on what he should do next. Don’t let his looks fool you though, he’s not just handsome, this boy is SMART with a dashing personality to match. Titan came to us all the way from Northern Manitoba where he was saved by Save a Dog Network after being found roaming all alone out in the cold and starving, from there he took a plane and was welcomed into our care with Pound Dog Rescue. It was clear that Titan had not had a full meal in quite some time and in addition he also had worms when he arrived so he was experiencing diarrhea. From the moment we brought Titan into our home it was clear that he had had some less than desirable experiences with humans as he was fairly skittish if we went in to pet him. It didn’t take him long to realise though that we were not going to hurt him and we were there to help him eat, grow and learn how to love. Titan warmed up to the dogs in the household immediately and was won over by the adults in teens in the home within hours. Titan is currently living in a home with adults and teens and he loves everyone very much. Titan is still unsure about super fast movements though, between him being unsure of fast movements and loud noises and the fact that he is a very large gangly puppy we are recommending a home with kids that are aged 10+ who are well versed in proper interactions with dogs and understand how to be calm and deal with a large puppy who may occasionally like to jump up or puppy mouth. Titan is also living in a home with several dogs, of all ages. Titan loves to play, he would play all day long if it was up to him. Running around the backyard or the house, playing keep away with toys or tug, or just some fun wrestle matches, this boy is up for it all. He is also quite content to find an open pet bed and chew on a toy all on his own. Titan has been very respectful of the older dogs in the home, he has on occasion tried to initiate play with them, but he respects their cues when they are not interested. Titan is still working on his confidence and right now he is still a very submissive dog when it comes to interacting with other dogs, it’s really important that if there is another dog in the home that it not be a dog that is super confident who may potentially bully him. Titan also has a cat in the home, our cat is very dog savvy and therefore we do not find her on the floor very often, but on the occasion when she has been around Titan has been fairly respectful of her and has shown moderate interest. I believe that Titan would be suitable for a home with a dog savvy cat, as long as his new owners are of the understanding that this integration could take many weeks or months for them to become compatible. Titan is fully crate trained, he goes into his crate for all of his meals, for bed time at night as well as when we are gone during the day. We have made Titan’s bed a very safe place for him and a comfortable place with blankets, because of this Titan absolutely loves his bed and has no issues with going in. Titan has always been super quiet in his bed and normally doesn’t make a peep. He will gladly lay down and wait, knowing full well that you will come and let him out when its time. It will be very beneficial for Titan to continue his crate training in his adoptive home so that he will always have a safe place that he can go to when needed, this can come in handy if you are having work done on your home and need him in a safe place, or for when you need to leave the house you know that he will be safe and not getting into any mischief. Titan is also 98% house trained! I say 98% because Titan has not yet figured out how to let us know when he needs to go outside to use the bathroom, but he is always going to the bathroom outside. Titan has done fairly well right from the beginning with this with only a few accidents, and the last few weeks have been completely accident free, we have Titan on a very consistent schedule for bathroom break currently. Titan has been on a few car rides during his time with us, and he has been a fantastic traveller! Currently Titan is in his crate in the back seat when we travel anywhere, and he will immediately lay down and not make a peep until you get to wherever you are going! Titan is very much an adventurer and that means that going for walks are one of his favourite things to do! Titan currently goes on at least 2 walks a day, sometimes these walks are on his own, and sometimes they are with the other dogs in the household, either way Titan is always up for the adventure! Titan is an excellent walker, if you keep engaged with him and provide the occasional treat you will have him loose leash walking from his martingale collar the entire time. There is the occasional time where he will pull from the end of your leash, but if you give him a few leash pops and continue to talk to him he will return right back to a loose leash again, which I then always reward him for. Titan loves all the smells and sights when he is out for his walks and he has been enjoying the many more squirrels, rabbits and birds that we have been seeing. He does sometimes get a little over excited for these animals, however talking to him and keep his attention re-directed to you is always a sure fire way to get through it! Titan is definitely looking for a family who is outdoorsy and loves to go for long walks and trail hikes, as this is something that he loves to do! Training is always a very important part of dog ownership, if not one of the most important things. It’s important that his new forever home understand that training is a lifelong thing and not just 7 classes and your done. There is always something to be learned to keep their curious minds working, as well it’s always good to keep up with their socialization and continue building that confidence! During his time with us I have enrolled him in some training classes to help him with building his confidence, and he has also shown that he has quite the drive to learn and wants to please. He is doing so well in his classes and I am so proud of him! Training is of course a requirement of our adoption contracts here at Pound Dog, however given Titans breed and how much he enjoys training, we are really looking for a home for him where someone will be committed to taking him through advanced levels of obedience and possibly move onto something like agility or a dog sport afterwards. As mentioned above, Titan is a very beautiful boy and he is certainly eye catching but he has so much more to him than just his looks. This boy is such a sweet soul, you can tell he really puts everything into anything he does. When he plays, he plays hard. When he sleeps, he’s passed out. When you’re working and training him, he is learning so well! He really does deserve the 10/10 rating for being the best boy, but shh don’t tell my dogs that. Titan has adapted so well to living in a home with us after being found wandering in the north, he now thoroughly enjoys the comforts of living in a home and having pet beds and couches to sleep on, he really loves to hang out and watch TV with you at the end of the night! This boy is always up for whatever you’re up for. Now that Titan is eating good food and having consistent meals, he is definitely starting to put on some weight, but it’s very clear that he still has a ways to go because his body is still constantly growing at this point! Its important that he be kept on a good high quality diet to ensure that he will continue to get all the nutrients that he needs to be able to grow big and strong. Titan has been in to see our vet and he is doing very well. We are looking for a home for Titan where he can either be the only dog or he can have a buddy as long as they are not too confident or pushy of a dog. His ideal home would have children who are aged 10+. I believe that Titan would do well living in most home situations, such as either a detached home, or a semi-detached as he does not make too much noise in his crate. His ideal home would hopefully have a fenced in yard for him to be able to hang out in the sun and run around to find some sticks to chew on. We are looking for a home where he will get lots of walks and trail hikes daily to help him work out his energies and someone who is committed to his training. If Titan sounds like the dog for you, then I suggest you submit an application today for this good boy! #rescuedismyfavoritebreed #rescuedog #adoptdontshop #pounddogs #pdr13years #pounddogrescue13yearsstrong Name: Titan ID # PDR1352 Age: 4.5mths Gender: male UTD vaccines: yes Breed: Bullmastiff/German Shepherd Colours: fawn, black mask Coat length: short House trained: yes Special needs: no OK with kids: older OK with cats: yes Ok with dogs: yes Status: adoptable Microchip: yes Size: large Location: Plattsville Adoption fee: $900
