Pet care experience

Caring for animals is my passion

Overnight stays available --I offer overnight stays in your home or mine for dogs/cats/pocket pets/farm animals Available for daily drop-ins and dog walks. I also offer ‘doggy-sitting’, baby-sitting for your dog (or cat!) usually 2h+. Message me for pricing! Professional dog walker and experience with dog training. Former vet assistant of 3yrs. I have been doing Rover for 4y now and absolutely love it!! I wish I could do it full-time. I once was asked to watch someone’s indoor pot-belly pigs and that was a dream come true! Growing up, I was always the neighborhood pet caretaker. I have experience house sitting dogs, cats, and birds. I have also volunteered at Aark wildlife rehab center in Chalfont, PA. I had a dog of my own and would’ve done anything for her. Dogs are my favorite animals, so I would do anything for any dog. I am very responsible and graduated college magna cum laude. I will treat your dog with respect. I offer a calm, gentle, empathetic approach which is especially good for anxious dogs. I understand that dogs have feelings too and are very intelligent beings that deserve no less than the best. All animals deserve an advocate and love. Taking care of any pet would bring me happiness. I do best with low energy dogs (senior dogs preferred!), but I have an understanding for all types of dogs needs and can adapt. I do enjoy having variety with the pets I watch! I love to travel so am willing to travel anywhere from 30m-1h out of my listed location.

Marissa was an excellent dog sitter! She kept me in the loop and sent me tons of pictures. She went above and beyond taking my senior pup on several adventures during his weekend with her. I would use Marissa again!

Marissa was wonderful with our large-breed Bernedoodle. He was so well cared for, and we received regular updates during our 5-day vacation. Marissa was a new sitter to Benny, but she jumped right in and loved him up. The house was perfectly cared for. We will definitely use her again!

Safety, trust & environment

I CAN have pets in my apartment. Dogs will have to be kept in a crate while I am out of the house, but cats will be confined to just my bedroom. Dogs cannot have separation anxiety and cry while I am away bc of my neighbors. If you live in the city, I require you have a designated parking spot or a guest permit for me to use. I will care for your pets as if they were my best friends because I love animals!

Pets

A typical day

I will play games with them, take them on walks, to parks, car rides, and teach them tricks. Cuddles and keep their routine. Hikes and for ice cream!

Cats
0 to 15 lbs
16 to 40 lbs
41 to 100 lbs
over 101 lbs
Dogs over 1 year old
Non-neutered males accepted, spayed females only
No females in heat
Marissa can host up to 2 pets per night
I would prefer to know if the dog is high energy, if they jump a lot, if they bark a lot, what triggers them, if they are counter surfers, trash-diggers, if they are territorial, separation anxiety/cry when left alone, how they do on walks, how they are for car rides, how they are at the vet, if they have ever bitten, if they mind their paws getting wiped, if they have food sensitivities, if they are a flight risk, what time they usually wake up, and if they are dog aggressive or not.
Each sitter joining Rover needs to pass a background check. And by booking on Rover, you can get photo & message updates, 24/7 support, and reimbursement for eligible vet care.
