DISCHARGE INSTRUCTIONS

Date: 04/03/2025

Procedure: Percy presented for a pre-scrotal castration (neuter).

Because Percy had general anesthesia today, he may be sleepy for the remainder of the day. Special care must be taken to protect him from falling down stairs, running into things, and exposure to hot or cold weather.

Incision Site Monitoring and Care: • Percy has an incision on his groin. Absorbable sutures were used under the skin. Please monitor the incision for any redness, bruising, discharge, or opening of the incision. If you are concerned, please do not hesitate to contact us and send a picture of the incision to [email protected]. • The incision site does not require regular cleaning. If the incision becomes soiled or dirty, gently wipe the area with saline solution or warm water and a clean cloth. Do not bathe Percy until the incision is healed. • Percy must wear an e-collar or surgical suit at all times until the incision heals. If he can lick, bite, or scratch at the incision, it may become infected, fail to heal, and require further surgical intervention. • If Percy is wearing a surgical suit during recovery, please check the suit daily to ensure it has not become soiled, which can contaminate the incision. Be sure to unbutton the suit at least once a day to visually inspect the incision for any signs of bleeding, discharge, heat, or pulling apart at the edges.

Dental Procedure:

Owner: Alexandra Oblak | Patient: Percy | Species: Canine | Breed: Havanese | Page: 1 of 3

While under anesthesia, we also extracted four retained baby teeth: three incisors and one premolar. Small sutures were placed at the gum line where these teeth were removed. These sutures will dissolve and fall out on their own. No special care or change in food is needed for this area.

Nutrition: Please feed half of Percys usual intake tonight. On occasion, transient GI upset will occur after general anesthesia. It is not uncommon for patients not to have a bowel movement for a few days after surgery. Please let me know if he is straining to defecate.

Exercise: Please restrict Percys activity for the next 2 weeks while the incision heals. This means no running, jumping, or rough-housing. When you are not home or at night, you may need to place Percy in a crate or small room.

Medications: 1) Carprofen 25mg tablets: Give ½ tablet (12.5mg) by mouth every 12 hours for 5 days. This is a non-steroidal anti-inflammatory pain medication. Please give with food. The first dose is due tomorrow morning. 2) You can give the previously prescribed Trazodone, as needed to help keep him calm, starting tomorrow morning. 3) You can give the previously prescribed Gabapentin, as needed for additional pain relief, starting at 8 pm tonight.

Additional Procedures: – We placed a microchip during todays visit. – We also performed a nail trim.

Follow-up: Please schedule an appointment for a nurse visit for an incision check in 10-14 days.

Thank you for entrusting the Small Door team with Percys care. If you have any questions or concerns, please do not hesitate to contact us.

Procedure: Riesling presented for a surgical spay. She did excellently! You should be very proud of your girl!

Because Riesling had general anesthesia, she may be sleepy for the remainder of the day. Special care must be taken to protect her from falling down stairs, running into things, and exposure to hot or cold weather.

There is a possibility of seeing a small amount of blood in the urine over the next few days. This is caused by the surgery and should resolve within a few days.

Incision Site Monitoring and Care: – Riesling has an incision on her abdomen. Absorbable sutures were used under the skin. Please monitor the incision for any redness, bruising, discharge, or opening. If you are concerned, please do not hesitate to contact us or send us a picture of the incision. – For the next 3 days, you may ice the incision for 10 minutes 3-4 times per day. If Riesling does not tolerate this, do not force her. – The incision site does NOT require regular cleaning. If the incision or abdomen becomes soiled or dirty, gently wipe the area with saline solution and a clean cloth. DO NOT bathe Riesling until the incision is healed.

Owner: Neil Corber | Patient: Riesling | Species: Canine | Breed: Labradoodle | Page: 1 of 3

– Riesling MUST wear her surgical suit at ALL times until the incision heals. If Riesling is able to lick, bite, or scratch at the incision, she may introduce infection, or the incision may fail to heal, necessitating further surgical intervention. – Riesling may need an e-collar if she is able to lick at the incision site despite wearing the surgical suit. – Please be sure to check the surgical suit daily to make sure Riesling has not soiled it, which can contam- inate the incision. – Please be sure to unbutton the surgical suit at least once a day to check on the incision directly to ensure it is healing appropriately with no signs of bleeding, discharge, heat, or pulling apart of the edges of the incision.

Nutrition: Please give Riesling half her usual diet this evening. You may resume normal feedings the day following surgery. Occasionally, transient gastrointestinal upset occurs following general anesthesia. It is not uncom- mon for patients not to have a bowel movement for a few days after surgery/anesthesia. Please let me know if she is straining to defecate.

Exercise: Please restrict Riesling’s activity for the next two weeks while the incision heals. This means no running, jumping, or roughhousing. When you are not at home or at night, you may need to place Riesling in a crate or small room.

Medications: 1) Carprofen 25mg Tablets: Give 1 tablet every 12 hours for 5 days. This is a non-steroidal anti-inflammatory pain medication. Please give with food. The next dose is due tomorrow morning. 2) You can give the previously prescribed Trazodone, as needed to help keep her calm, starting tomorrow morning. 3) You can give the previously prescribed Gabapentin, as needed for additional pain relief, starting at 8 pm tonight.

Follow-up: Please schedule an appointment for a nurse visit for an incision check in ~10-14 days.

Discharge Summary for Peanut Procedure: Eyelid Mass Removal (Right Eye) Date: March 27, 2025 Veterinarian: Dr. Eliza O'Callaghan

Peanut did great today during his procedure to remove a small mass from his upper right eyelid. He was placed under anesthesia, and the mass was successfully removed. He woke up smoothly and has been comfortable throughout his recovery. The mass was sent for biopsy, and the results are expected in 7-10 days.

At-Home Care Instructions: Activity & Incision Care: • Peanut should wear an e-collar (cone) at all times until his follow-up visit to prevent him from scratching the area. • Keep him calm and limit activity for the next 10-14 days to allow proper healing. Avoid rough play or rubbing his face on surfaces. • Check the incision daily for redness, swelling, discharge, or signs of discomfort. If you notice any of these, please contact us.

Medications:

Owner: Chelsea Hart | Patient: Peanut | Species: Canine | Breed: Mixed Breed | Page: 1 of 6

1) Carprofen (pain relief): Give half (1/2) a tablet by mouth every 12 hours for 5 days with food. If he experiences vomiting, diarrhea, or dark stools, stop the medication and call us. 2) Ofloxacin Eye Drops: Administer 1-2 drops to the right eye every 12 hours for 7 days. Start tomorrow morning. 3) You can give the previously prescribed Trazodone, as needed to help keep him calm, starting tomorrow morning. 4) You can give the previously prescribed Gabapentin, as needed for additional pain relief, starting at 8 pm tonight.

Diet: Feed Peanut half of his regular dinner this evening and resume normal feeding tomorrow. It is not uncom- mon for pets to experience transient GI upset or a reduced appetite after anesthesia. Let us know if he won’t eat tomorrow, or if he is straining to defecate or has diarrhea. Some pets may not have a bowel movement for a few days after surgery—this is normal and usually resolves without intervention.

Follow-Up: • Please schedule a recheck appointment in 10-14 days for an incision check. This will be a nurse visit. • We will reach out with the biopsy results as soon as we have them.

PATHOLOGY (as of Mar 30, 2025)

TEST RESULT REFERENCE RANGE/COMMENTS

Biopsy Source: SKINSQ_MASS -

Biopsy Type: EXCISIONAL -

Clinical History: on medial portion of upper eyelid OD 3mm patch of mildly erythema- tous skin w/ slight hypotrichosis

-

Pathologist's Report INTERPRETATION: Haired skin upper eyelid region: Lymphohistiocytic nodule strongly

-

Owner: Chelsea Hart | Patient: Peanut | Species: Canine | Breed: Mixed Breed | Page: 2 of 6

favoring a regressing cutaneous histiocytoma with rare foci of mild lymphocytic epitheliotropism (see comment) Surgical margins: Completely ex- cised

COMMENTS: Histopathology of this mass re- veals a dome-shaped nodule con- sisting of admixed infiltrates of small mature lymphocytes and background populations of histi- ocytes. The favored interpretation for this lesion is a cutaneous his- tiocytoma in the late stages of regression. Extensive lymphocytic infiltrate is a key feature of re- gressing histiocytomas. There was a mildly atypical feature of multifo- cal lymphocytic epitheliotropism for the hair follicles in this tu- mor. Epitheliotropism can be a feature of cutaneous lymphomas however the epitheliotropism in this case was an inconsistent and relatively subtle finding. In com- bination with the concurrent his- tiocytic infiltrates the overall his- toarchitecture of this lesion and the minimal atypia or mitotic ac- tivity of the constituent lympho- cytes the likelihood of a cutaneous lymphoma is considered very low. Nonetheless if additional similar skin lesions are noted to emerge or this patient develops evidence of a regional lymphadenopathy further investigation into this differential diagnosis should be considered.

Furthermore due to the admix- ed with histiocytic nature of

Owner: Chelsea Hart | Patient: Peanut | Species: Canine | Breed: Mixed Breed | Page: 3 of 6

this lesion other differentials for lymphohistiocytic inflammation of sterile or infectious (e.g. fungal infection mycobacterial infection) etiology also cannot be definitively excluded; however these etiologies are considered significantly less likely.

Canine cutaneous histiocytomas are common and largely benign skin neoplasms of dogs derived from epidermal Langerhans den- dritic cells. Histiocytomas typically present as solitary lesions of young dogs most often under 3 years of age although older animals can also be affected. Frequently af- fected sites include the pinnae muzzle extremities and scrotum. Purebred dogs are predisposed and boxers and dachshunds are overrepresented. Multiple histio- cytomas occur in less than 1% of cases and are more common in the shar pei breed.

Histiocytomas often grow rapidly and epidermal ulceration is com- mon. Lesions may regress sponta- neously and complete surgical ex- cision is typically curative. Local in- vasion and lymph node metastasis have been reported in rare cases of single cutaneous histiocytomas. Cutaneous histiocytomas in the ear canal of dogs may represent a par- ticularly aggressive variant with a case study reporting locally inva- sive behavior.

Internal Interpretation ID: IXD5.1

HISTOPATHOLOGIC DESCRIP- TION: Haired skin eyelid region: This lesion is a focal moderately well demarcated raised dome-shaped mass of densely aggregated small mature lymphocytes with admix- ed superficial infiltrates of histio- cytic cells. The overlying epidermis is mildly hyperplastic and multi- focally extends short slender rete ridges into the underlying cellu- lar infiltrate. Along the superficial aspects of this mass with histio- cytic cells are most densely clus- tered there is frequent karyorrhec- tic and pyknotic cell debris. Very rarely dermis and epithelium dis- plays evidence of mild infiltration by small mature lymphocytes.
