Thinking of becoming a dog walker (self employed)

[Careerchangehat]

Ive found 2 short courses from New skills academy.

Dog walking and pet sitting (also one module will tell me what i need to run this business) diploma, 15 hours, 23 modules.

Also pet 1st aid cert, 3 hours, 7 modules.

Would this be ok to start my business up or do i need more depth diploma and cert?

Thanks

Also its a cpd course
