Do I have the right to have a dog ?

Hi everyone, I’m a 38 yo woman, married without kids. I’m struggling with a lot of issues. I’m on antidepressants and I also have motor problems (can’t walk for very long, can’t get out of the bed very long some days etc). I’m struggling with a dread feeling of loneliness (I want to end it sometimes), and I want the compagnie of a little dog so badly (for a few years know). I don’t know if I can allow myself to have one because I’m not able to be a very good mama (can’t walk him every day for very long etc)

What’s your experience (if you have any) with this subject ? Do you have a dog yourself ? How is it going for you two ?

(Please excuse my English and thank you, any input would be appreciated).
