divider-multiprintThings to Know When Owning a Toxirn:

Food & Diet Requirements 🦴

The Toxirn will need a good-quality kibble that meets the nutritional requirements of a small and active dog. Follow the feeding directions for your dog’s weight on the package and don’t overfeed your dog to avoid issues that develop from obesity. You may have to try a couple of different foods for your new puppy as they sometimes develop digestive upset if their food is changed. If you’re uncertain what kind of food to feed your puppy, ask the breeder what brand they have been feeding the dog. If your Toxirn experiences digestive upset, a visit to your vet may be needed to address the issue.

Exercise 🐕

Toxirns are high energy and require at least 30 minutes of activity a day to keep them happy and healthy. A daily walk is encouraged to maintain their weight and keep them fit.
