An impossibility. If there is no consent there is no "suicide", assisted or otherwise.
The term for what is done to pets and research animals is "euthanasia" — is that consensual? Or even "assented" or "acquiesced" to, if you want to side-step the question of how informed one has to be for it to count as "consent".
Pets are not people and cannot consent. Euthanasia is not assisted dying. There is no 'assistance' when one party doesn't share the goal. Straw man.
The previous comments, the link text, the article on the other side of the link, and the Canadian members of parliament debating this law all used the term “euthanasia”, so no, it is not a straw man.
