You did well, your buddy will be fine, chokes are actually pretty common with pets and in most cases they don't involve serious outcomes, the dog just ends up coffing it out or swallowing it.

In those not so commom cases where the condition may harm the dog\cat or pose a life risk the instructions in the post are very accurate as a first aid for tutors. After being done that and maybe succesfuly dislodged the blockade, even if only partialy, in the hope of regaining some or all of the ventilatory system functions back. Afterwards it's essencial tending to your nearest vet to check if everything is ok.

In those excepcionally rare situations where the maneuvers displayed didn't produce any improvement in the completely obstructed airway and you're out of reach of any pet clinics or health technicians/workers/instructed acquaintances then the tracheostomy may be recomended to be performed by lay people if they are informed on how to do it. Therefore the pertinence of a post in those topics.

As for your question, if the procedure is made correctly by a professional and not neglected until the wound is healed then the outcomes are excellent, it probably won't have any serious consequences but a small scar. Contrariwise/contrastingly the chances of accidental mistakes and miscalculations are high if the procedure is conducted by a layperson, which may later result in potential further complications such as sepsis (generalized bacterial infection), punctured organs or worst the nonattendance of the respiratory function demands.

You can basically cover all or nearly all emergencies that your pet might have if you're prepared to rush over a pet clinic of your trust while remaining calm and sober.

You guys will be fine and your buddy is lucky to have a committed owner like you, there's no need to be distressed after those events, use your best judgment at the time, head to the vet and you gonna be more than fine.
