- Tracker's breed is rather inconsistent. He has been said to be a Chihuahua [1], but the Nickelodeon Parents website states he is a potcake dog. He is also a bit too big for a Chihuahua, as he is about the same size as the other pups.
- It generally would make more sense for Tracker to be a potcake dog. If he were actually a chihuahua, he would be smaller than Skye, which in the show, he is not.
- Like Everest, the only special he was absent was in "Ready Race Rescue".
- He is one of the two major additions in Season 3, along with the Air Patroller.
- He is Carlos' pet and lives with him in the jungle.
- He is the second bilingual character in the series, speaking fluently in both English and Spanish.
- The first is Francois, who is the only bilingual human on the show being fluent in French and English due to the fact that he comes from France.
- He is the first bilingual member of the PAW Patrol, as well as the first bilingual animal on the show. The second one would be Rex.
- Tracker was first-deployed with Chase and Skye in "Tracker Joins the Pups!".
- He the second secondary character of the PAW Patrol to have a superpower as a Mighty Pup (though it was only shown in some toys), the first being Everest.
- As depicted in some of the toys, he was supposed to have a sort of plant-related superpower. It is unknown what his power was supposed to do.
- Despite having a toy version of his Super Paws and Air Pups uniform and vehicle, he still has not appeared in any Mighty Pups or Air Pups episodes, save for a brief cameo in "Mighty Pups".
- Conversely, despite appearing in "Jet to the Rescue", Tracker has not received any toys depicting his uniform or vehicle from that special.
- Tracker was first-deployed with Rocky, Rubble and Marshall in "The Pups' Winter Wonder Show".
- Tracker finally first-deployed with Everest in "Jet to the Rescue".
- Tracker and Zuma were first-deployed in "The Pups' Winter Wonder Show". However, it was with the other pups at the time.
- Tracker has been deployed for backup with Rubble and Zuma in "Pups Save a Giant Plant".
- Tracker finally first-deployed with Zuma in "Jungle Pups: Pups Save a Hum-Hippo".
- Tracker has been first called for a mission 22 times.
- Tracker has been deployed for backup 9 times.
- Tracker has been called into action (either a first-deployed or deployed for backup) 31 times.
- Tracker is scared of the dark (proven in "Tracker Joins the Pups").
- He's also afraid of Jack Scallywag, as shown in "Sea Patrol: Pirate Pups to the Rescue".
- Tracker has the best hearing out of all the pups.
- The multi-tool function in his Pup Pack contains what appears to be a Swiss army knife.
- Like Everest, he does not live with Ryder and the main pups at the Lookout. He acts as a second reserved member of the PAW Patrol being called on when his skills (in tracking) are required.
- His jeep can convert into a pup house in "Pups Save Monkey-dinger", but in "The Pups' Winter Wonder Show", "Pups Save Big Hairy" and "Pups Save Baby Humdinger", if he is deployed at the Lookout, he has to jump into another pup's vehicle to go his vehicle.
- In the PAW Patrol Live!: Race to the Rescue stage production, Tracker was confirmed to be 4 years old, meaning that he is the youngest member of the PAW Patrol.
- Tracker mentioned one of his relatives in "Sea Patrol: Pirate Pups to the Rescue", and became the first pup to mention his relatives, in his case, his GrandDog (grandfather).
- In the same episode, he shows that he knows how to read music and play a flute.
- He is the fourth pup to lose his Pup Tag in "Sea Patrol: Pirate Pups to the Rescue" and "Pups Save Little Hairy"; after Marshall, Skye, and Everest, respectively.
- Tracker is the sixth pup to stand on his hind legs, in "Tracker Joins the Pups!".
- Zuma is the first in "Pups and the Ghost Pirate".
- Rubble is second in "Pups and the Ghost Pirate".
- Rocky is third in "Pups Save Alex".
- Marshall is fourth in "Pup-Fu!".
- Skye is fifth in "Merpups Save the Turbots".
- Chase is seventh in "Tracker Joins the Pups".
- Everest is eighth in "Pups Save a Teeny Penguin".
- It is unknown as to why Tracker was by himself in the jungle. He may have also been lost, abandoned, or forgotten similar to Everest. He was seen with a red scarf when he first appeared, but it's never been said where (or even who) he got it from.
- Whenever he is listening carefully to something, beeping sounds can be heard akin to a radio device.
- Before he joined the team, he only wore a red bandana.
- It probably was given from his grandpup that was mentioned in "Sea Patrol: Pirate Pup to the Rescue".
- Tracker is one of the few pups who enters their pup-house vehicle cockpit from the inside, as he shows up in the control section of his jeep after going through his pup-house entrance.
- In his debut episode, he has been shown to have a fear of Nyctophobia (darkness).
- Later in "Pups Save Thundermouth", his fear was decreased a little since Skye went with him in a cave.
- Even though Tracker does not like spooky situations, in "Pups Save Thundermouth" Tracker mentions he enjoys listening to spooky stories.
- Despite not making an appearance in the sub-series, he has a DLC outfit for Aqua Pups in the new game, PAW Patrol: World.
- He also wears several other outfits such as a Halloween costume, sports uniform, and Rescue Knights uniform that he has never worn in the series alongside Everest.
- Currently, unlike the PAW Patrol, as well as Everest and Liberty, he is not featured on the official PAW Patrol website's character guide page.
- He is, however, featured on the kids' version of the website.
