I was interessed in this anime ever since it was announced, and it was not only an amazing surprise but it also became one of my favorite animes. But unfortunately, most people did not gave a chance to this. So this review is to convince you to watch this show.
The story of dog signal follows Miyu, a guy that was dumped by his girlfriiend who gave him a puddle cub as a form of ''making him feel better'' about the break up. But our pour guy has to deal with a dog that does not listen to him and behaves really badly. One day while taking the dog to a walk, he meets with Shinichirou Niwa, a very skilled dog trainer that starts helping him. But since Miyu does not have money to pay for the tuition of the training he starts helping Niwa with the shop that was almost going bankrupt, due to the trainer rude manners with the clients.

The story is very simple, but is the execution that makes this anime expetacular. During the series, we see Miyu help Niwa with the training of all types of dogs and owners. Most of the owners are vey well developed as a characters, because as Niwa says: ''in the majority of the times, the dog behavior is the owner fault''. All the stories we see are very relateble and realistic and even if this is a cute anime, it does not run away from the dark themes if is needed. And by saying that, of course i mean that at some points in the anime they talk about animal mistreatment and the dogs lifespan. If you are a dog fan, you are going to cry as much as i did. Even the humans face a lot of challenges, such as family abuse and social anxiety.
The dogs are all very cute! the animation does an amazing job in combining a more realistic style with a more cute and anime like one. I think this anime does a better job in being a cute anime about animals than most i have seen. But of course your enjoyement will depend on how much you like dogs. But honestly i think is impossible to finished this anime not liking this cute creatures.

The main characters are very likeble and well developed. The more you learn about them, the more you want to see their progess. Miyu is an amazing lead and is always a joy to see how much he wants to improve his relationship with his dog Sanju. Niwa is a little too rude sometimes, but as we see more about him we start to understand and like him more. Risuka, a pet groomer, and Suzunosuke, a veterinarian, are Niwa's best friends and a big part of the anime and are also amazing characters. The side characters are also very well built, and even after the problems with the dogs are resolved, they continue to appear. All the characters have an amazing evolution, and you may end up liking some characters you dislike it in the beginning. And of course, the dog training is a big part of the anime and a way to teach people about it. Is a anime similar to Cells at work, trying to teach something to people in a funny and cute way. I absolutely adored all the lessons about training and if you have a dog i'm sure you will like it too. The opening and ending are super cute and talk about the love between an owner and his pet. The soundtrack in the anime is also okay. The animation is not perfect, but good enough for an anime like this, at least there never was a moment i tought the animation was bad. ▶ Overall, this anime is perfect from start to end. Is the best anime for animal and cute things lovers. Please give it a chance, you won't regret it. I'm hoping for season 2 because i could never get enough of these cute dogs! I already want to watch all over again!
