If your dog has chewed through an electrical cord, the first thing to do is to determine the extent of the damage and whether your dog has ingested any of the cord. If so, seek immediate veterinary advice. If not, you may be able to repair the cord yourself by cutting out the chewed section and splicing the wires back together. Alternatively, you may need to replace the whole cord or the appliance, especially if the cord is old and brittle. To prevent your dog from chewing electrical cords in the future, you can try strategies such as hiding cords, using bitter-tasting sprays, providing alternative chew toys, and teaching commands such as leave it.

What You'll Learn
Cut the chewed section out of the cord
If your dog has chewed through an electrical cord, you may be able to repair it yourself. However, if the cord is old and brittle, or if there is extensive damage, it is best to replace the entire cord or the appliance. If you are uncomfortable doing this yourself, seek professional help.
If the cord has only sustained minor damage, you can try the following repair method:
- Cut the chewed section out of the cord using a wire cutter.
- Slip a four-inch Heat Shrink Tube over one wire.
- Separate the wires by about two inches.
- Using a wire stripper, strip about one inch off the ends of all four wires.
- Slip a Solder Seal Wire Connector over one of the wires.
- Twist the two wires together, ensuring that they are matching wires.
- Move the connector so that the middle solder ring aligns with the middle of the splice.
- Using a heat gun, heat the middle solder ring so that it melts.
- Repeat the previous step for the other wire.
- Heat the other two rings so they melt and shrink.
- Rotate the connector so that the heat is applied evenly.
- Move the heat shrink tube over the connectors and apply heat to the tube until it shrinks, rotating the cord to ensure even heat distribution.
As an alternative to steps 11 and 12, you can use electrical tape to cover the connectors.

Slip a heat shrink tube over the wires
If the heat shrink tube is too tight to slide over the wire, you can try stretching it by using needle-nose pliers or chopsticks. Alternatively, you can cut the heat shrink tube lengthwise and glue it back together, but be aware that the glued area will not shrink under heat.
Once the heat shrink tube is in place, use a heat gun or another heat source to shrink it and create a tight seal. Keep the heat source moving back and forth along the length of the tubing to avoid damaging the wire. Continue heating until the tubing is tightly secured.
Now, move on to the next step of the repair process, which involves twisting the wires together and soldering the connection.

Strip the ends of the wires
Stripping the ends of the wires is an important step in repairing a chewed power cord. Here is a detailed guide on how to do it:
First, make sure you have the right tools. You will need a wire cutter or utility knife, and a wire stripper. You may also need a small screwdriver to separate the wires if they are twisted together.
Once you have the tools, start by cutting the chewed section out of the cord with the wire cutter, ensuring you remove any damaged parts of the wire. If the cord is old and brittle, it may be better to replace it entirely. Be sure to cut at least two inches away from the damaged section to ensure that no compromised wire remains.
Next, separate the wires inside the cord. If your cord has three or more wires, be sure to keep them in the correct order so you can match them up when twisting them back together. Strip about one inch (2.5 cm) off the ends of the wires using a wire stripper. Be careful not to nick or cut the wire itself, as this will impact the conductivity of the wire.
Now that the wires are stripped, you can twist them together with their matching partners. If the wires are different colours, make sure you twist like colours together. For example, twist the two green wires together, then the two white wires, and so on. If there is any exposed wire outside of the twist, trim it with your wire cutters.
Finally, cover the repaired area with electrical tape or a heat shrink tube. If using a heat shrink tube, apply heat with a heat gun until it shrinks and covers the repaired area. Test the cord by plugging it into an electrical outlet.
By following these steps, you can safely and effectively repair a chewed power cord by stripping and reconnecting the wires.

Twist the wires together
If your dog has chewed through an electrical cord, it is important to act quickly to prevent further damage and ensure safety. Here is a step-by-step guide to repairing the chewed section by twisting the wires together:
Step 1: Cut and Separate the Wires
Start by using a wire cutter to cut and remove the damaged section of the cord. Ensure you cut out a few inches on both sides of the chewed area to guarantee that you are working with intact wires. Separate the wires by a couple of inches to provide ample room for stripping and twisting.
Step 2: Strip the Wire Ends
Using a wire stripper, carefully strip about one inch off the ends of all the exposed wires. This process removes the insulation, revealing the conductive metal underneath. Make sure you strip an equal amount from each wire to ensure a secure connection when twisting them together.
Step 3: Twist Matching Wires
Now, it's time to twist the wires together. Be cautious to twist only matching wires, typically identified by their colour or markings. For example, twist the two black wires together, the two white wires together, and so on. This ensures that the electrical current flows correctly through the repaired cord.
Step 4: Apply Connectors and Heat Shrink Tubing
Slip a Solder Seal Wire Connector over one set of twisted wires. Position the connector so that the middle solder ring aligns with the middle of the splice. Repeat this step for the other set of twisted wires. Additionally, slide a Heat Shrink Tube over one of the wires before twisting to provide insulation and protection.
Step 5: Heat the Connectors and Tube
Using a heat gun, carefully heat the solder rings of the connectors. Start with the middle ring, melting it first, and then move on to the outer rings. Ensure even heating by rotating the connector during this process. Afterward, slide the heat shrink tube over the connectors and apply heat until it shrinks, providing insulation to the repaired section. Again, rotate the cord for even heat distribution.
Final Checks and Precautions:
Before plugging the repaired cord into an electrical outlet, inspect your work to ensure a neat and secure connection. If you are uncomfortable with any part of this process, it is best to consult a professional electrician or consider replacing the entire cord. Always prioritize safety, and if your pet has chewed near the plug, it is recommended to replace it entirely.

Apply heat to the tube
If your dog has chewed through an electrical cord, it is important to act quickly and safely to repair the damage. Here is a step-by-step guide to help you fix the chewed cord:
- Start by assessing the damage. If the cord is old, brittle, and easily cracks, it may be better to replace it entirely.
- If the cord is relatively new and in good condition aside from the chewed section, you can repair it. Cut the chewed section out of the cord using a wire cutter. Be sure to cut out all the damaged parts to ensure a safe repair.
- Now, slip a four-inch Heat Shrink Tube over one wire. This tube will act as a protective covering for the repaired section of the cord.
- Separate the wires inside the heat shrink tube by about two inches. This will give you room to work and make the necessary connections.
- Strip about one inch off the ends of the wires using a wire stripper. This step is important to expose the fresh wire so you can make secure connections.
- Slip a Solder Seal Wire Connector over one of the wires. This connector will help create a secure and insulated connection.
- Twist the two wires together, ensuring that you are twisting matching wires. For example, connect the neutral wire (identified by a white stripe or writing) to the neutral wire on the other side of the cut.
- Move the connector so that the middle solder ring aligns with the middle of the splice. This will ensure an even application of heat and a secure connection.
- Using a heat gun, apply heat to the middle solder ring until it melts. Then, heat the other two rings until they melt and shrink. Rotate the connector as you apply heat to ensure even melting and shrinking.
- Repeat the previous step on the other wire. Ensure that the connections are secure and insulated.
- Now, it's time to apply heat to the heat shrink tube. Using your heat gun again, move the heat shrink tube over the connectors and apply heat until it shrinks. Rotate the cord as you do this to ensure even shrinking and a secure fit.
- Finally, test the repaired cord by plugging it into an electrical outlet. Ensure that the repaired area is neat and secure before plugging it in.
By following these steps, you can safely and effectively repair a chewed electrical cord. Remember to take your time, work carefully, and always prioritize safety when working with electrical components.

Frequently asked questions
First, determine the extent of the damage and whether it would be more prudent to replace the entire cord. If the cord is old and brittle, or if your dog chewed near the end of the cord close to the plug, it's best to replace it. If not, cut the chewed section out of the cord using a wire cutter, then separate and strip about one inch off the ends of the wires using a wire stripper. Twist the two wires together, slip a solder seal wire connector over them, and use a heat gun to melt the connector. Finally, test the cord by plugging it into an electrical outlet.
Try to keep electrical cords out of your dog's sight and reach by hiding them behind furniture or running them through PVC pipes. You can also use cable ties and hooks to keep cords off floors and flush against walls. If there are cords that your dog has access to that you can't hide, you can try applying bitter or spicy-hot tasting sprays to deter them from chewing.
If you know or suspect that your dog has been electrocuted, immediately shut off the electricity to that cord. Do not touch your dog if you cannot turn off the electricity—you could also get electrocuted. Use something wooden to move your dog away from the cord. If your dog has ingested part of an electrical cord, contact your veterinarian for advice.
