Can my dog get sick from separation anxiety during a long trip?

Updated on September 23rd, 2025

Pet's info: Dog | Maltese | Male | neutered | 4 years and 3 months old | 5 lbs

My dog and I are very close, he follows me everywhere. I left for a night and my mom told me he was playing but he was also waiting by the door for me, he got sick the day after (he didn't pooped for 2 days) I have to leave for 5 months and I was wondering if my dog can get sick If I leave him for that long. My 3 siblings that love him and my parents are staying with him.

I am sorry to hear about Olly! Pets can sometimes become depressed when their owners or friends leave. I wouldn't expect him to become sick though. If he seems severely affected there are some options to help him with his anxiety at being separated from you. I would consider having them get an Adaptil collar or diffuser for the house which is a pheremone products https://www.adaptil.com/us/Adaptil/Adaptil-Collar and a calming supplement such as Composure for dogs https://www.vetriscience.com/index.php?l=product_detail&p=900780060 or Zylkene http://www.vetoquinolusa.com/content/zylkene. If he is still having problems despite these products then your vet may need to prescribe prescription medication for him.
