Thanks to the Rosetta mission, our understanding of comets has greatlyimproved. A very good opportunity to apply this knowledge appeared in early2017 with the appearance of the Jupiter family comet 41P/TGK. We performed anobservational campaign with the TRAPPIST telescopes that covered almost theentire period of time when the comet was active. In this work we present acomprehensive study of the evolution of the dust environment of 41P based onobservational data from January to July, 2017. Also, we performed numericalsimulations to constrain its origin and dynamical nature. To model theobservational data set we used a Monte Carlo dust tail model, which allowed usto derive the dust parameters that best describe its dust environment as afunction of heliocentric distance. In order to study its dynamical evolution,we completed several experiments to evaluate the degree of stability of itsorbit, its life time in its current region close to Earth, and its futurebehaviour. From the dust analysis, we found that comet 41P has a complexemission pattern that shifted from full isotropic to anisotropic ejectionsometime during February 24-March 14 in 2017, and then from anisotropic to fullisotropic again between June 7-28. During the anisotropic period, the emissionwas controlled by two strongly active areas, where one was located in thesouthern and one in the northern hemisphere of the nucleus. The total dust massloss is estimated to be $\sim7.5\times10^{8}$ kg. From the dynamicalsimulations we estimate that $\sim$3600 yr is the period of time during which41P will remain in a similar orbit. Taking into account the estimated mass lossper orbit, after 3600 yr, the nucleus may lose about 30$\%$ of its mass.However, based on its observed dust-to-water mass ratio and its propensity tooutbursts, the lifetime of this comet could be much shorter.
