ELI5: How come states have issues getting the drug cocktails to commit executions but everyday vets put down animals humanely?

I guess I am confused why it is difficult to put down a person but easy for animals, different drugs used?

(This is not a political question regarding capital punishment, I am only confused by the paradox)

Executing criminals is done in a stupid and over complicated way because people are upset with the idea that a criminal could somehow enjoy being killed if any opioids are used but also the constitution won't let them actually actively torture the criminals so there is a weird and multi step process to make sure they die in a way that is not painful but also not at all comforting. 

Animals we just overdose with barbiturates which is a death of feeling good and falling asleep and not waking up ever.
