Is the word tutores the same in Brazilian and European Portuguese?

No

While the fundamental legal and academic meanings of "tutores" are identical in both varieties of Portuguese, there is a significant difference in typical usage regarding animals. In Brazil, "tutor" has become a popular and common way to refer to pet owners, as it is seen as a more respectful term than "dono" (owner). In Portugal, the word "tutor" is almost exclusively reserved for legal guardianship or educational/academic contexts; a Portuguese person would rarely use "tutor" to refer to someone who owns a pet. Additionally, while the word "tutores" is spelled the same, related words often have spelling differences (e.g., acadêmicos in Brazil vs. académicos in Portugal).
